'Add to This Catalog' on Export Not Creating Temp Collection

[Bigg Uhpp]

I've tried with multiple photos, but no joy. This was working two days ago. Now not. 

TIA

What Temp Collection?

More accurately, in the Catalog panel, Added by Previous Export is supposed to appear at the bottom of the panel. Checking Add to This Catalog is supposed to create it. I then put these into a collection typically named Ready to Publish. It's worked til now when it's simply not.

I cannot replicate this behavior, in Lightroom Classic 13.1, Windows 11. What is the version NUMBER of your LrC? What is the version number of your Operating System? We need version NUMBERs and not words like "latest" or "up-to-date".

LightRoom Classic 13.1

MacOS  13.4

It’s working for me, but my versions are slightly different:

Lightroom Classic 13.1

macOS 13.6.3

I’m not aware of any changes in macOS that would cause a difference here, but it’s worth updating macOS just for the security updates…

Lo and behold, Added by Previous Export is appearing and being populated once more. Quit LRC, restarted MacBook, and voila. I cannot detect neither cause nor correlation. 

Thanks for all the help.
