Audio Pan is keyframed automatically to the left on all clips

[TimSchijf]

So after about 4 weeks of working in this project. Suddenly all clips suddenly had a keyframe enabled and turn -100 to the left. Anyone know how to fix this and why this is happening. This happened on all 100 sequences, on all 1000 mutlicam sequences and every audio track (which ranges from 3 to 12 tracks per take). Also back ups do not work it will apply this keyframing as soon as I open the project.
