No option to change paragraph sizes in individual product description.

hello,

as per the below image, is there a reason options for paragraph 1,3 & 4 are not listed here anymore?

The below is a snippet from an edit product section.

I'm sure it used to be the same as this below image, which has the options for para 1,2,3&4.

Apologies if i'm missing something very obvious.

if anyone has any ideas, thank you!

p.s i also have no idea why mac super key options are showing in the first screenshot, as i'm on windows.
