attempting to place dimension between holes keeps placing diameter dimension

I am running 2017 SP5.

I have never seen this before but suddenly as I attempt to place dimensions between 2 holes I can select the holes and get the distance but when i place the dimension it gives me a diameter of the first hole.

Has anyone seen anything like this before?

Video attached. I tried placing it like a picture but that doesn't work?
