Bugs in content types

I'm using H5P multichoice questions for a Drupal quiz, and have discovered that for questions with multiple correct answers, the user's response is not evaluated correctly during the quiz. This problem only seems to occur on touch devices (verified with iPhone 6 and recent iPad so far). Some additional details:

Sound does not currently work in the SingleChoiceSet 1.1 on wordpress.

Issue: Line 24 in sound-effect.js - version is set to wrong file path therefore files are not found.

    SoundEffects.libraryPath = H5P.getLibraryPath('H5P.SingleChoiceSet-1.0');

Changed to correct version and works fine. 

Hello,

I've found that in the drag and drop text content type, the last letter doesn't appear in the exercise. You can read read more here.

Thank you!
