The past few times I've batch plotted a particular project, the letter "X" does not print, nor does the "&" or ":" symbols... Among others. This seems to be a problem only with this one file, however, if my coworker opens the same file up on her PC and batch plots, there are no problems. I hadn't opened up the file in a few weeks, and when I went in to make some updates, I was able to plot with no issues. I opened the file again toady and, again, no X's. 

I've attached a screenshot sample. The text should read: 

Kitchens (eXcept suite)

Brand: Fisher & Paykel

Model: RS32A72J1
Finish: Panel Ready
SiZe: 31-1/8"W X 23-11/16"D X 71-7/8"H

As a note, this hasn't happened in any of my other files. 

I've been working with cad for over 5 years. I had CAD for Mac 2016 until about 6 months ago when I upgraded to 2018. Never used to have any problems but now there seems to be some weird bugs.
