Incorrect type size showing


I'm wondering if anyone else has come across this issue? In the past week, the type size hasn't been displaying properly in any of my documents. In this example, I've highlighted a title which is actually 31pts, however it shows up as being 12pts, with the actual size of the type in brackets after. I have paragraph styles set up for all the type styles in the document, and I'm unsure whether the problem has started in there?
Thank you!
