file changing names ? and being deleted

[fatdjsin]

hey hope someone can help.. been using ffs for a couple years now. never had a problem before but now its causing havoc in my files ...

i sync my pc win 10 with my macbook pro via my home network.

before the problem :
file A is song A
file B is song B
file C is song C

after the problem
80% of the 3000+ mp3 and flac did sync
20% is fucked up

with this pattern
file A is now SONG B
file b is now Deleted ...gone ...

so the file A is playing song B ... plays ok but has been renamed to a song that is deleted

(i hope i got this right sorry im a french speaking dude)


... hope i get a fix here :(
