I am trying to add a Bootstrap class of hidden-md, but because I've tried hidden-md-up and hidden-md-down (both of which I believe are Bootstrap 4), I can now not add hidden-md, as when I hit Enter, I select the auto-suggested option.
In the image attached you'll see that Layouts is suggesting hidden-md-up, and when I hit Enter, that's the option selected.
As a workaround:
1. Add abc-123
2. Save and reload
3. Try to add abc-1 ==> will not work, as such, hit Return, this will add abc-123 again
4. Before leaving the editor now continue typing and add abc-1 and hit return.
5. Remove the abc-123 if desired with the little "x"
As soon we do have a fix for this known BUG, I will update you here with news.
Thank you for your patience.
This is not yet solve.
I am pushing the developers to look into this ASAP.
We now have an erratum for this issue with the workaround as well, where you can follow the progress:

We will update that Erratum as soon it's solved, so we can close this ticket here.
