CVpal issue

I’ve had my CVpal for a longtime, never had any issues. The other day when I started using it the tuning was completely off. When I checked the voltage it was sending out it was WAY off from proper calibration. I re-calibrated it but now when using a mode where Note CV is coming from OUT 1 it won’t go below .5V. As in the lowest note it will play is F#1. When using a mode that sends Note CV from OUT 2, it works as expected. OUT 1 and OUT 2 are calibrated exactly the same. Has anyone come across this issue?

Thanks
