File folder name changed to maintain 1 file but the synced maintain 2 folder file including old one

I have changed file folder name in my phone. After, I synced my file on my lap top. Later, after sync the old file name appear and now I have 2 files instead of 1 file updated rename. Any steps I missed?

Can you post the seadrive.log messages when this happened?
