Did you turn on the font resizer for the module? I didn't have the problem at first, so something had to have changed in the background, and I haven't done anything as far as I can recall. But you were going to do the font resizer for the module, so that it wouldn't be such tiny print.
If you've activated that, try deactivating it and we'll run an experiment to see if that helps.
Meanwhile, here's a test of the first and the third dice-roll module shortcut -- I think these are only multiple shortcuts, they seem to produce no differences, purely a {roll}{/roll} command.

And for comparison, here's me simply typing out the code.
