Bugs in content types

I have the activities in WordPress, in "H5P Content" and they work perfectly. I load them in my LearnDash courses within WP, the problem is that after a while the activities are no longer seen within the course, and I get the error that says that the activity with ID: 21 (example) could not be found, and so on with all the activities. 

While in H5P Content nothing seems to have changed, it is like then the activities are no longer recognized. 

Cada vez que subo H5P a mi WordPress cambia el ID de las actividades y no se pueden encontrar más dentro del curso de learndash. Qué podría hacer?

Cannot find H5P content with id: 21

Every time I upload H5P to my WordPress the ID of the activities changes and no more can be found within the learndash course. What could I do?

In some servers, the H5P content is not displaying and i am seeing the below error in error console.
