Salvaging seem bugged

So while Salvaging some gear i didn’t need i noticed that one of the aspect i imprinted onto my gear has lowered the % after the last salvage i did, that doesn’t seem right they shouldn’t go lower due to salvaging only improve or u need to redo how salvaging works because I’m not looking to mess up my %'s by salvaging useless gear with lower %'s

This might be a bug? I don’t recall reading anything that says this would happen. Report it?
