Spotify constantly deletes GBs of offline tracks on my android

[fozcam]

I accidentally download an album on my pc on spotify and my offline tracks on my phone deleted. It seems normal bur the problem is i don't have a third device. So ı didn't violate the device limit. So why the hell my 25 gb of archive just wiped? I have to download hundreds of albums one by one again. And it always happens its not first. I realise now its because ı download albums to pc. Please help me ı don't want this happens again.
Note : ı use spotify family so this ia the problem? I don't think so because my brother only have a phone and ı have pc and phone so after all 3 devices isn't violating the limit
