Traktor Timecode issue

encountered a strange issue for the first time last evening and I can't seem to find any info on it, for some reason, every time I load a new track into the right channel and start playing, it played at about -20%, and I had to switch the turntable over to 45 and pitch it down about 7.5% on the turntable to get it playing regularly. tried recalibrating the control vinyl, restarting traktor, using a different control record, the box in timecode preferences that reads "turntable speed []45rpm" was not checked, and the other channel was playing tracks normally.. nothing on my setup has changed since the last time I used it, and it was really frustrating, yet I haven't been able to find another mention of this anywhere, perhaps due to terrible googling skills or odd search terms. any thoughts?
