Can't select field source, or enable dynamic link in dynamic text SPPB 6.5 & 6.6

hi - all the details are there, and in hidden section. You don't need a screenshot as you have to go to the page I suggested and test the selection of the new page options, specifically the ones I pointed out.

All the details are in the first post. Screenshots not needed. Is this an automated response ?

Go to pagebuilder admin.

Look for Health Index Page Test Holistic, open.

Try to select source. Nothing happens.

Enable dynamic link and try to select / open source options there. Nothing happens.

Login details should be working, tested before I posted. Will test again.

( after checking ) Login details work fine, as originally posted.

I was testing what you'd set up and it worked as it was supposed to at first, but about 10 mins later, as was happening for me previously, trying to add a new dynamic content page, or a new article page, a window opens up with the previously set up items but greyed out and no option to create a new item in those options, despite working ok only 10 mins beforehand.

Am I doing something wrong or missing something ?

I think you need to add the info in creating collection index page, that you need to already have created a collection, which is not mentioned, and had me puzzled for a while. No mention needing to do that first in the opening explanation of the creating collection index. Just a suggestion.

I'm not understanding the whole collections / filters / conditions thing yet.
