Using Autocad for Mac 2016.

When I look at my drawing in .pdf format, I notice there is no space between fraction and the whole number on my dimension lines. In some cases, the fraction covers ones place digit if it's a multi-digit whole number. It's almost as if there's only a certain amount of room for the dimension to fit. If it can't fit, it gets squished.

The numbers appear just fine in both model space and paper space.

Please see attached .pdf.
