Which version of Lightroom do you have?
Does that happen with all the fonts?
It should be the most current version (Lightroom CC 2015.3 Release).
No, it does not happen with all of the fonts...just two specific "text boxes" seem to be having this issue. I suppose my next course of action is just to delete, and re-type.
Are you using the same font on each page? If so go to the menu and choose:
Edit >> Select All Text Cells
Then select your chosen font again in the right-hand Type Panel
Unfortunately no...I think that is part of the problem. I am using different versions of a purchased font. So even in the same text block, same word even, there are different fonts right next to each other.
