Scaling fail, invalid result body?

I have a part I’m trying to scale up, approx 300%, but it’s giving me an “invalid result body” error.

I didn’t have a problem scaling it down in another project space, drawn natively in Shapr. I then exported it as a STEP (needed STEP for another software, Cadmio), then imported the STEP into another Shapr project. Now it won’t let me scale it back up.

Edit: I was able to scale up the original project in Shapr. Is this issue only caused by STEP objects imported into Shapr?
