Bugs in content types

How can I make the count of true-false answer TOTALS show only the total true? I am not talking about the individual answers, which clearly are either true or false, not something in between. I am referring to the total score at the end of a series of such questions. Is there a way for that to show the toral right (or wrong) instead of the total true subtracted by the total false? The total of true-minus-false is meaningless.

when i edit the course presentation and when ambed this presentation not load and display message content not available, I work width theme WPLMS, please help

I am getting these errors on the console:

TypeError: H5P.Transition is undefined
TypeError: H5P.DragNDrop is not a constructor

I already did the required PHP settings (memory and upload) and enabled the mandatory modules as you can see on my phpinfo page.
