PC-DMIS won't create an auto-circle

I have created a plane (1) and am attempting to create an auto-circle for a hole on that plane which is .098" in diameter. My probe is 3mm. So while yes, I understand the error message (Sizes for a contact feature should be greater than probe diameter.) I should be able to create a 1 point circle on that plane and have done this successfully in the past many many times. Any ideas what might be going on here?

And sorry, running 2017 R2 sp6... that recently updated... wonder if thats what is causing this to not work all the sudden.

since the hole is .098" it really doesn't matter what size of probe I use since all of them are too big. (3 mm is approximately 0.11811") When you specify a plane and then place an auto-circle on that plane you have (in the past) been able to take a 1 point circle. PC-DMIS then calculates the size of the circle by how far the probe goes past the plane. However things like burrs or small imperfections create issues with getting an accurate size using a 1 point circle. Which all of that is irrelevant. What is relevant is the positioning of those holes when drawings specify GD&T. Thus my attempt to do a 1 point circle.
