Why aren't the dimension numbers appearing?

Hello guys, I haven’t been able to hang out on the forum for a long time because of the busy work.
A problem i have had many times, i run into when working on step files. The dimension numbers are weird, when I double click and open the window, I can see the dimension, but other than that, the numbers are hidden.
Has anyone encountered this before?

inch was a millimeter error, it was fixed when foreign step files (usa) made inch inches to millimeters.
Thank you Rob
