Bugs in content types

Greetings!

The function to left-align text in Course Presentation/Dialog Card is not working correctly.  I select the left-align function button and apply it to a paragraph of text but it centers the text instead. Right and center align work as expected.  Here's my example:

I am using Chrome, on a MacBook Pro and have seen this on both h5p.org and my own Drupal 7 instance.

When Creating a single choice set in a Course presentation, and disable the sound effects, The show Soultions button doens't work, and when you update againg that content sometimes the show solution and the retry buttons don't work

1. Create a Course Presentation, Create a Single Choice set Activity, Uncheck the "Enable sound effects" option
2. Moodle, H5p.org
3. Desktop
4. Chrome
5. 1.5
