(DDJ-200) Faulty Channel Fader Controls Volume of Both Decks

Hey! Having a weird and downright irksome problem with my DDJ-200. From out of nowhere, my left channel fader has begun to control the volume of both decks. Additionally, my right channel fader hardly affects the deck's volume, moving the rekordbox fader a fraction of bar up or down at best. I've tried resetting the midi configuration Many times and I've cleaned out the sliders to no avail. I've seen this problem posted once before ( https://forums.pioneerdj.com/hc/en-us/community/posts/360062862612-DDJ-SR2-Channel-Fader-Controls-Both-Channel-Volumes ), unfortunately without a workable response. Seeking urgent assistance!
