Bugs in content types

Hi everyone, 

I've been getting to know the exercises and am loving H5P. Currently working on a version of the trial site. I am having  difficulty getting the frame area correct so all of the elements sit in the same frame - trying to avoid the scroll down button.  I've adjusted all of the size options, but I can't seem to get the entire activity to fit in a single frame, so the user needs to press the RHS scroll down button to select the "check" button.  

It seems to be an issue with the resizing. I think I'm asking about the relationship between:

I have some custom javascript that is supposed to be triggered on Fill in the Blanks questions (consisting of several blanks) when the user checks the answer. Previously, using the getScore method like this worked: if(event.getScore() != null){

When i create some text in the course presentation text editor and center it, the text stays centered after saving (see attachment before).

however when i go back to the text object and apply bold/italics or a header style the text does not stay centered anymore and can't be made centered again, only by recreating the text object without styles.
