Preview Window Does Not Change to New Reference

Endnote 21.5 on Windows 11
I see that the preview window is now able to be horizontal. This is a great addition, but there is a tremendous bug. I can open the preview window (either horizontal or vertical) and cannot scroll through the references. The preview window stays open to the originally opened reference. I have to “x” it close and reopen (double click) the next citation. If I double click a new reference, nothing happens. I have to “x” out before a new reference pops up. This is just silly.

Am i missing something?

Thanks,
Chris
