Bugs in content types

Hello.

I'm using my h5p contents created in  wordpress under the subdomain. I'm embedding all of my contents in the posts of my main domain. in this post you can see that all the contents are appearing except the last one which is a "course presentation content". all of them are embedded by using iframe from the same subdomain. I don't know what's wrong with it. can anyone give some ideas what to do ?

When trying to download the h5p file to reuse, it creates some junk character and does not create a download file. 

I am using the wordpress plugin v 1.15.3

Hi, I have created several Quiz Question Sets. There is one problem: when I answer the questions on my Android Phone, I will not be able to view the scores at the end if I have about 50 questions. If I have three questions I can view my scores at the end. In both situations I can view the results in PC. Is this a bug or is there a limited number of questions for viewing mobile scores?
