Bottom height being displayed incorrectly

[FrodoLoggins]

Bottom height is displayed (by the blue line) on the same Z level as my selection. However, I've offset it -.01". The bottom height (blue line) does not display .01" below my selection UNTIL I remove and then reapply the -.01" offset:

EDIT: I've been experiencing this a lot lately. It appears like the generated/programmed bottom heights are where I want them to be, the issue is just with the blue preview line/plane when in the Heights tab.

Hi @FrodoLoggins 

I checked and on my laptop that doesn't seem to happen. I'll test another couple of files to see if I can trigger the same behavior.

Thanks
