Slider T

What does a “T” means on a slider?
I know that “S” is for smooth but can’t figure out “T”
and when that T is on, I have unsuitability receiving MIDI for that slider

That’s what happens when you have MIDI Take Over enabled.

It is “off” for me but I still see this. Anything else I can check?
