Bugs in content types

Hi, 

I got this bug with the pluging in Wordpress( Please see picture) : NOTICE: UNDEFINED INDEX: LIBRARYID IN C:\USERS\MCHHAB\DOCUMENTS\WEBSITES\WWW.SITE.DEV.CC\WP-CONTENT\PLUGINS\H5P\H5P-PHP-LIBRARY\H5P.CLASSES.PHP ON LINE 1963

Could someone help please?

Thank you in advance for your support. 

After installing the new beta branching module, none of the libraries load, making it impossible to add any new content. All existing content is working, but cannot be edited either. I am attaching a screenshot of what the java console is showing me. 

In drag-and-drop using chrome, I'm getting image stretching with both JPEG and PNG. What's the best way to uploaded/formatted an image?
