Bugs in content types

In the content type: " Interactive Videos", the window does not look correct. Buttons are missing and the content is out of place. In the browser console, I get the following error message: The property "name" is missing in the field 0. (h5peditor.js:423:16) Do you have any idea where the problem could be. I can't find anything  about this

 H5P: 1.15.3

 Firefox: 93.0 64Bit

 Wordpress: 5.8.1

 Macbook Big Sur

1. Detailed steps to reproduce the bug (exactly how and when did it happen)

a.Create a dialog card with some text. Notice that the default text justification is left aligned.
b.Save and view the dialog card. The text is centered.

Expected behaviour: The text should respect the justification settings!

None of the H5P drag-and-drop content types work on the SmartBoard. I tried using Google Chrome, Mozilla, Internet Explorer. Is there a way to fix this or any workaround to get it working on a SmartBoard? I have implemented all the solution suggestions at https://h5ptechnology.atlassian.net/browse/HFP-3063. The result has not changed. I also tried it on different operating systems such as windows, linux. The result has not changed. This problem needs to be resolved immediately.
