Text box issue in presentation

Hi Folks

I did a search to see if this issue has been discussed before.

Using Moodle v 3.9 content bank, various browsers incl CHROME, Edge.  H5p Plugin V (uncertain)

The last couple of days I've been encountering a problem with text box - When creating text regulary (but not constant) as I go back into edit I get a compressed text box (Please see attachment).  The solution is to save current work, exit content bank and then re-enter 50% of the time I will get access back to the normal Text box.  This will however happen again within the next couple of times I create text.

Fairly confident this will configure correctly within a few days but thought i would raise it.

I am currently only working on Presentation not sure if this is carrying into other content types.

Any Ideas?

Kind regards 

Jay
