responsive project and learning interactions - text scaling and wrapping help

Hey everyone, I'm working on a responsive project using the 3 default breakpoints. I'm hitting a wall with the Checkbox learning interaction (LI).

It isn't wrapping text or scaling text if the text is too long to be displayed at that screen size. It just gets cut off.

Mobile breakpoint example:

If you change the LI font size in any of the 3 views, that font size is applied to all of them. So if I set a tiny font so the whole line appears on mobile, the tiny font is used at desktop size.

I don't have the 'Scale Text' option in the LI config that some other posts have talked about.

In general, I've found the Responsive process rather unintuitive and difficult to use, but I've figured out how to work around pretty much everything but this.
