SOLVED: How to get rid of class from container?

Sorry I’m lost here - how do I get rid of no-italics from the container element class please?

Very weird that it’s showing up in the all the chapter 1+ Containers when I only applied it to plain text elements in chapters 49 + … I see it in this code above but I don’t know where even in the Bricks Editor where to get rid of that … there must be a global container setting I have to fix up. Checked the Bricks academy but I couldn’t find instructions on it.

Many thanks
Carl

EDIT: After looking through the templates where I added that code, I removed the span code with the no-italics from the plain text elements, and the popups & pages all appear back to normal. What I’ll have to do I think, is to add some rich text elements and set them the exact same formatting so that will be safer.
