Problem with attached pictures

Hello, lately I have encountered an issue in Obsidian that I didn’t have before. Every time I attach a screenshot to a note, this neither shows up in the note nor goes to the “attachment” folder I have selected, but it remains hidden among the general notes. At that point, I need to manually drag the link inside the note, and move the file to the attachment folder.

The only change I can think of is the fact that I have moved my vault inside Dropsync, but I have subsequently opened Obsidian selecting the moved vault. Anyhow, all other folders work without problems…
Did anybody encounter the same issue or has some ideas?
