Markings in Lightroom Mobile are not shown in the sync folder on Lightroom Classic

I use Lightroom Mobile for culling my photos und mark the photos I want to keep. Therefore, I sync my Lightroom Classic folder in a collection. After syncing they appear on Lightroom Mobile, Lightroom or in the synchronized folders in the Internet.
However the markings done with Lightroom Mobile I only see in Lightroom or in the synchronized folders in the Internet, but not in Lightroom Classic.

Any suggestions?

Now I deinstalled Lightroom from my PC and moved the lightroom catalogue from my OneDrive folder to a local folder. The pc was running over night and everything is fine now.
