I at first was blaming my buddy for this thinking he was clearing my filters on yellow chests, but then I noticed it happening on Gleba as well while he definitely wasn't on with chest I KNOW I had previously applied filters to (science packs). I'm not entirely sure what the cause of this is, but my guess is that it might have something to do with relaunching the game or transferring ownership of the save file (in otther words, my buddy would host some times, but then would need to go before I need to so I would save the game and then host on my side for when he got back)

Thanks for the report however without a way to reproduce this there’s nothing we can do.
