This is with 37.0 beta 4 on Windows 11
At the bottom of the Related Verses - Key Verses section in a Topic Guide there is the option to Open n passages in preferredBible to filter the Bible just to show those verses

But if I click this with the section not fully expanded (above it is just showing five of the eight verses) the Bible is filtered to just those five.
If I expand the section

and then click the Open in button then all of them are used.
This doesn't seem to happen in the corresponding section in either the Factbook or Sermon Starter Guides - all verses are used as the filter irrespective of how many are shown.
