Looking for a few ideas to find the cause of this issue.

Been having lots of strange behavior in drawings the last couple days. There are a few dimensions on a somewhat complex sheet metal part I'm detailing that for some reason will show dimensions that are many times too large, the same edges want to display as an angle, so I'm having to use vertices to attach them. You can see the two edges I've selected and yet I get this crazy angle dim. The dims that show as too large also have "little arrows" on the leaders that are not consistent with the rest of the drawing. The problem is consistent after rebooting the PC.

I cannot share the files, as I don't have permission. In the instance shown I'm off of a formed edge to the edge of a flange. All the bends in this part are 90°.
