I am using Joomla 5.1.0 and SP Page Builder 5.4.1. I can open and edit the SP Page Builder pages in the backend editor, but the content of a Text AddOn is displayed a bit strange: https://img001.prntscr.com/file/img001/eYbv8-8KRhmuQ45rQ0K7uw.png

Nothing is displayed in the frontend editor: https://img001.prntscr.com/file/img001/g9BR3UfOQryJYeshfUtZHw.png

I haven't changed anything on this page for a long time, so I don't know exactly when the problem started.
