## Issue

A multi-page submission is incorrectly matched to more than one Structured layout, resulting in pages that are split among different layouts.

## Affected versions

All versions

## Affected configurations

All configurations

## Causes

Multiple duplicate layouts or layout variations are part of a live release.

## Recommendations

- Make sure that the desired layout is part of a release.
- Check for duplicate layouts.
- If there are multiple similar variations of a layout in a release, use layout identifiers to uniquely identify each variation and increase the machine’s confidence.
- Make sure that you use the same number of layout identifiers across all variations of a layout.
