If you are using Notion 6, you will want to look at page 7.10 of the User Guide. You need to make sure that you put the tempo marking in brackets before entering your text as a descriptor. I just tried this on my machine running Windows 10 and it seems to be working as designed. Make sure that you haven't changed any of your global font sizes under Full Score Options. If you continue to have an issue, you may want to submit a support ticket by logging into your my.presonus.com account and clicking on "Support."
