Steps to reproduce:

1. Add a new Basic Web Content 'test'.
2. Add an Asset Publisher to a page.
3. Click on AP's three dots -> Configuration. Set Asset Selection to 'Manual'.
4. In Asset Entries section, Click on 'Select' -> Basic Web Content.
5. In the new  modal window, set the Display Style (upper right option) to 'Cards'.
6. Select 'test' and click 'Add'.

Expected result: 'test' is added to the selected asset entries.

Current result: nothing is added.

*The same behaviour is observed when selecting assets in Collections.
