Not able to customise text int GrapesJS

Your software
My Mautic version is: 4.0.1
My PHP version is: 7.4
My Database type and version is: MySQL

Your problem
I am trying to create a very simple text email using GrapesJS HTML builder. Seems like all my customisations don’t go with the email test as shown in the image attached.

What I am missing?

Hello @tiagomatosweb,

There have been several new versions of Mautic since your post.
Can you update Mautic, clear the cache and create a new email and tell us if you still have a problem like this?

If so, can you please copy/paste the HTML code generated by Mautic?
