Error after installation

Hi

Today, I installed via wordpress plugin. 

• I am using MasterStudy theme with WPBakery. It's a multisite.   
• I can create content, import demos and can place it on a page/post. No issues.
• The H5p content shows when I "preview" the page /post. 

Problem 

• The H5P content does not show when I publish a page of post.  ( During the preview, it is visible)

I am attaching 2 jpg files.  The error indicates towards  " H5PIntegration / missing translation).

----

Other issues I observed;

• During creation of content in h5p, picture uploads from computer but not from media folder.  (seems to have implication on reference /name of file)
• In Gutenberg , there is no option to place the H5P content. However, it is available in WPBakery builder. It has button which directly takes to H5P and has insert key. (Just FYI)

----

• Checked multiple themes including twenty-twenty, divi and others.
• Also, tried uploading directly and reinstalling / unistalling etc. Tried various methods like checking full screnn etc.

Need your support. Thanks
