Why there is always a modified dir before start syncthing?

Hi, I am new here. First thanks to the this great software, it helps me a lot in my daily work.

I use syncthing to sync files between my LAPTOP and phone. Every time when I start syncthing, there is always a modified dir shown in Recent Changes, which is not modified indeed.

This issue do not affect my sync job, but it should not happen. How to fix this problem?

no reply. is it not clear? or gonna delete this topic.

To me it’s but clear at all what is happening here. And as it’s at most a cosmetic issue and my bandwidth is limited, I didn’t engage (and don’t beyond this). Others may have similar reasons.
