Text box bounding box sizing issues?

Hey all, Hope everyones doing well.

Ran into this weird one and im a bit stumped on whats happened. Same as the image Linked states. (I think) since the semi recent Dynamic text function was added to the pop out bar, the text box has changed size by default to always be over sized (mostly in vertical spacing) when it originally used to be like the bottom size (edit text mode bounding boxes)

Nothing looks off in the paragraph/Character settings so im a bit stumped. Hopefully its just a daft little button needing changed but had a search and couldnt see anyone else talking about it online so potentially just a me issue 😅
