Starting with the release of Strategy ONE (March 2024), dossiers are also known as dashboards.
In Strategy 2020, chapter filters are limited to 100 results for the initial incremental fetch, regardless of what the display style is. Scrolling to the end of the result box will get you another 100 results.

The limit is not configurable for chapter filters in dossiers. This is being investigated by the Strategy Technology team and an update will be provided as soon as possible.
