Rich Text Editor - "Extend to Fit" Missing

Hi all — We’ve been WAY behind on upgrading our version but as I upgraded to version 20 today, I noticed that our Bubble Rich Text Editor has started “extending to fit” (which is the opposite of how we had it setup before).

More than that, I noticed that the plugin has lost the “extend to fit” button. On the help page, it says that it exists, but I’m not seeing it.

this is a major problem for us because the RTE is tiny when it should be 4 lines (how it’s always been for us).

Here’s roughly what we want it to look like (Scribbled out a name):

Here’s what it looks like now:

Thanks for any help!

EDIT: I was in Plugin version 1.9.6

And trying to upgrade to the latest.
