I have quite a few Channel Configs that I use for C5, C6 and C7 Corvettes. This week I had to tune some of each. No matter which Channel Config I opened, it would show MPVI.2 > PLX but as soon as I started scanning it would disappear. I tried a bunch of different Channel Configs and it did it every time.
If I deleted that channel and reinstalled it, then it would work. I just want to understand what is going on here. It was a royal PITA.
