Layout dimension "tightenfactor0" error

Here’s the problem… when creating dimensions in a layout, and ‘faking’ the dimension value “tightenfactor0” is inserted. See screenshot.
I have just done a full reinstall, and it’s still happening.
Has anyone seen this issue?

Hi Rob -

I’m not seeing that here. Can you post a simple file that behaves like that on your system?

I’m not able to replicate it in a clean file. It seems that it comes from the geometry in the file. I’ll repost an update when the problem comes up again.
