Classic Course Player Edit Issue

Summary

Cannot edit the html on a classic page. We get random html and script code in the course description.

Content

The course can be viewed via the classic course player; however, if you attempt to edit the course, you receive the following error script. You cannot access or edit the file path in the HTML code. (See image below.)

It is not a special characters issue that we can tell it has done it on courses that have special characters and courses without any special characters.

This has happened to older courses, newer courses, and updated courses. We have had this issue on our staging site first and then in our Mexico/ Spanish LC. We have even uploaded two courses (almost identical) and had it do this on one but not another.
