Bugs in content types

Hey there, I'm putting a series of videos into a course presentation. To ensure my text and video is in the same place I'm cloning the last page. What happends though is that if an interaction from the previous video is located PAST the end of the new video embedded (stay with me) I can see the pink spot but I cannot access it to delete it! Any tips?

Hello everyone,

I have a problem/bug that i want to share it with you and find possible answer. I have a website, with h5p interactive content question sets, where an user has two complete the quiz atleast 2 times to see his/her improvements. The problem is that when an user completes the same question set, only one ( probably the latest ) score is stored in the database and shown in the results page. What i need is for the database to save all the scores. I tried surfing throughout the code by myself, but can't seem to find the answer.

Hello,

I have some drupal pages with course presentation library content. They all were working great but some of them stopped showing. The page loads ok but the content built with course presentation library does not show. This bug does not make a problem with all my course presentation pages but some of them stopped showing. 

Thanks,

Update in the issue:

I have some error notes from developer tools:

js_rG9E0AcFJKwXbL2drG5kGogWOTce2KeYYrP-I4HJ20U.js:130 Uncaught SyntaxError: Invalid regular expression: missing /
