Can´t disable "reuse" in Moodle

Hello,
I use H5P in Moodle.
If I disable the checkbox for to show the "reuse" download, this will not be saved.
The "reuse" otion is displayed. When I return to edit, it is checked again, allthough I unchecked and saved it.
I had the same issue in Wordpress.

Thank You in advance for any hints, Stephan
