And this is being fixed? You would know, right? Being a Cadence person and all. I would consider this a significant bug. A feature that makes things easier then breaks other stuff. I would call that bad, just bad.

The display of a circular pad fails if the pad contains just 1 arc.
Shape -> circular in the menu creates a 1 arc pad. The workaround I suggest is to re-create the .ssm by using add shape polygon, set to arc, at 180 degrees angle and a radius of what
size you need. This stores the data with 2 arcs which the display code
will draw properly.

I ran into a problem building a symbol with a padstack containing .ssm's built using shape circles, rather than the old style of building circular shapes by connecting arc segments. Mostly because that's my option in 15.2
I built the .ssm I created the padstack, the geometry was shape and I added the name using the shape selection block I created the symbol and placed the pin :PROBLEM: no visible shape came through, but I can detect on the area I know that I placed that pin and it informs me that a pin exists in that area, allegro lets me create a .bsm and .dra file with no errors I pull the symbol into a board file, :PROBLEM: no visible pads on the component, but once again allegro informs me that the pin does exist in that location. I ran adb++ from that board, and the pins were visible in the output.
I repeated the process, this time using rectangular shapes, "NO PROBLEMS". Pin pads were visible in the symbol, Allegro, and in the output.
Has anyone else run into this? If so are you getting around this successfully? How so?
