not a hundred percent synchronization

The synchronization process hangs on one value, although the files seem to be synchronized ok. In the first case, I set up some folders so that the computer only sends them, and the other two devices only receive. The idea is that when one of the devices receives the files, it will later transfer them to the other device if the computer is turned off, and this seems to work fine, but the phone does not show one hundred percent synchronization and it is a little annoying


In the second case I have an Obsidian folder, on the phone I set the folder to receive only and on the computer to send only, nevertheless I always have small unsynchronized files. What can I do to get rid of this?
