Bugs in content types

Sorry for my english, 

Since I've update H5P, many exercises are not displayed on my wordpress site. Someone have the same troubles ?

config :

WP4.2.4–fr_FR

H5P 1.5.3

When editing the image hotspot question type we're getting the 'loading semantics' loader but nothing else. I've attached an image of the error in my console on chrome. Can anybody help?

Thanks

Hello,

I just created a memory game and in the example, there are not bullets, but for some reason on mine there are. You can see it here. Am I doing something wrong or is this a bug?
