Identify a problematic book override, roll back reader preferences in stages, and verify files and bookmarks separately from presentation.

Unexpected scrolling or image counts can come from old reader overrides. Establish a working reference and record values before clearing a book or device scope. Reader-preference clearing concerns presentation, and its current prompt must be distinguished from deletion of comics or application data.

## Establish the affected scope

Compare the problem book with a working reference, keeping file identity and scene fixed. One affected book suggests its override; several call for device or general-scope inspection. Note recent changes without assuming causation from timing alone. Establish scope before restoring broad defaults.

## Record values and a return point

Record mode, orientation counts, scope switches and relevant gestures without exposing account details. Keep a chapter, scene and working bookmark, and test menu access. This settings note helps reconstruct preferences but is not a complete backup of comics or reading records.

## Disable the override before deleting values

Disable the book override temporarily and inspect the same scene. Improvement narrows the issue to the override; no change calls for checking defaults and mode conditions. Disabling is not proof of deleted values. Preserve this comparison and note an unsuitable default separately rather than repeatedly toggling without observations.

## Clear only the identified book scope

Use the current clear-this-comic reader-preferences control only after identifying its scope. Avoid comic deletion, local-copy cleanup or data restoration flows. Inspect values and behaviour afterwards. If the control is absent, check context and stop with the temporary-disable result rather than choosing a broader similarly named action.

## Consider the device scope only when justified

Inspect device overrides only if several books remain affected after book-level checks. Record local values and compare disabling before clearing. Keep another device unchanged where useful. A reset cannot be assumed to reconstruct an old personal configuration; its purpose is an understandable baseline from which to rebuild justified differences.

## Verify three practical actions

Test forward/back, menu open/close, and zoom/restore, then reopen the entry. Rebuild a necessary book override one value at a time instead of copying the entire problematic combination back. Verify the actions actually affected rather than treating one successful page turn as proof of every reader operation.

## Check content and records independently

Reopen the recorded bookmark and inspect content availability separately. A preference rollback is not a full file-integrity audit, and one working bookmark does not validate every download. State the limited successful result. If a scene differs, check identity and content changes rather than expanding reset scope blindly.

## Acceptance and the retained record

Finish with a stable repeatable baseline, recorded old values and an identified or narrowed scope. If behaviour persists, retain reproduction steps, version and mode rather than uninstalling first. Use the book/device/general sequence to investigate, not as an instruction to reset all three every time.
