Files missing, 20 synced more than 70 in directory

Nextcloud version (eg, 18.0.2): 19.0.1
Operating system and version (eg, Ubuntu 20.04): Docker

The issue you are facing:
In the directory on the host there are 74 files in my files directory, all permissions seems correct, in the synced folder on the clients there are only 20 files.

Is this the first time you’ve seen this error? (Y/N): Y

I don’t know what logs to check for this…
