as a pre-text I have just recently upgraded to windows10 & SolidWorks 2016 SP3.0 on a brand new lenovo P50 - there are some quirks I'm having and most I have been able to work around and find solutions too. This one is a bit different and I've not seen it before.

I have a 6mm hole that in the actual model there is a tolerance fit associated with this hole (R8 if you're wondering). The limit dimensions should be 5.99 [.2356] and 5.97 [.2349] respectively. When I use model items and then within that select "dual dimension" I get something a bit funny - my top dual dimension is still in metric while my bottom dual dimension is in the correct inch format!

here is where it gets real fun - if I just use the standard smart dimension to get the initial diameter call-out and then click "dual dimension" it displays in the correct format!

does anyone have any suggestions or ideas on why this might be happening. I have attributed this to my upgrading of just about everything and potentially a setting issues but I have gone through the settings and cannot seem to find anything that would change or resolve this.
