Synchronization Issue: 22 photos are still being synced

Hey Guys,

since I've moved to Lightroom (from previous old desktop version) I see a synch-error in the upper right corner for 22 pictures. I am not able to fix it and I have no clue which 22 pictures are causing this. Did anyone have the same issure here? Would appreciate your guidance to fix it.

Thank you so much

Jakob
