Exportable Text Area in Course Presentation

When we use "Exportable Text Area" in the "Course presentation", set rich text in the "Comments", and tick "Include comments in the exported document", the comments in the exported document loses its format.

I'm using Moodle 3.9, but I can see the same issue from Moodle 4.1.

I checked both library versions.
Course Presentation (1.25.5)
Exportable Text Area (1.3.15)

It used to work, and found it works with old versions.
Course Presentation (1.24.1)
Exportable Text Area (1.3.11)

Hi I recently upgraded my moodle site from 3.11 to 4.1 and everything went smoothly. I am think though I am going to  have to roll it back to 3.11 again because not one of the H5P activities copied over with moodledata and all the courses are devoid of any H5P activities. Before I do a roll back is there an easy way of accessing my H5P content and getting the activities to load in the courses as they were in the 3.11 version of moodle. 

I was really excited about upgrading and really thought that H5P was complatible with Moodle 4.11

Hello, I just noticed that H5P contents disappeared from the Admin area and navigation bar, all these contents can be shown up in the front-end, but in the admin area, they are invisible. even this page /wp-admin/admin.php?page=h5p is inaccessible to any roles who are permitted to access the admin. I have switched the theme to twenty-twenty and deactivated all plugins, H5p contents are still invisible.
