Why does Advanced Custom Field app change font size and format?

[girlbroda]

Used this app to create `tabs` within my product page and when I try to insert copied text the app changes the font size and formats. The paragraph has no formatting at all, used Cntrl+Sh+V to paste to ensure it, yet it still defaults. Sometimes it adds it correct and then my next block will be super small. This app does not (crazily) allow you to manipulate the font outside of heading bars. Has anyone figured out how to get around this??
