Custom sensors randomly changing?

So I went ahead and got a HWInfo license because I have custom water cooling and one of the sensors I want monitored is not possible without it. Or at least it's easier to just pay $20 a year.

Anyway, I've got it setup how I like it. I didn't really care much for it looking fancy as long as it is functional.

Perfect. Works exactly how I need it. Shows me everything I care about. But randomly it'll change the GPU Usage graph to like GPU clock speed. The little table at the bottom will sometimes just randomly swap around what it's showing?

Now sure what's up. I've gone in several times today and changed it back. And what's pictured now is what I want. I'll reply to this if it gets messed up again. 

Anyone have any idea what's going on?
