Strange audio level issues in rekordbox

Hello everyone and rekordbox support. I am using Windows 10 with the latest Rekordbox update and latest windows update. The following issues do not occur on my wife's PC which is identical to mine.

I semi-recently (around 3 weeks) started experiencing audio level issues in Rekorbox, with and without my DDJ1000. The issues are as follows:

1. When pausing and restarting a track (on any channel), audio levels for that channel increases significantly, when Master Tempo is on. Disabling MT resolves this, and it seems to not occur with it off to begin with. It sometimes requires restarting twice (pause->play->pause->play) or only once.

2. When changing the Key of a track, using Key sync or manually, audio levels of the channel increase significantly. When returning to the track's original Key *this persists!* until disabling MT (if it was on) again. If MT was off, the volume still increases significantly when the Key is changed, but is returned to normal upon resetting the Key.

3. Lowering the Low EQ of a channel causes the audio levels of that channel to behave unexpectedly and usually increase in volume.

I will note that any volume increase shows on the master audio, as well as observed on OBS so this is not simply a display bug. The tracks do not sound louder, however. These issues are infinitely replicable (as they occur every single time), I would have no issues recording audio and/or video examples.

I am quite dumbfounded by these issues, I believe they have to do with some audio/video driver, but I have no idea how to pinpoint and fix it. I have tried to reinstall (as well as delete the Rekordbox preferences at the Roaming folder during reinstallation), which did not help at all.

I would appreciate any help! Thank you for your time.
