Bugs in content types

Hi how are you doing??!!

I installed H5P in Moodle 3.1 and it works fine, the only problem I encounter is that for the drag-and-drop exercise, the background image is displayed by taking up the full width of the screen and does not respect the predefined size in the configuration (800 px).
How can i fix this?

I am unable to install true false and flash card library and showing msg (Failed to download the requested H5P.).

If any have solution please help.

I've previously used Drag and Drop with success, but recently I've encountered the following issues:

• drop zone highlighting - the correct drop zone always highlights as the user hovers over it, when drop zone highlighting is set to "never"
• all correct answers are marked as being incorrect.

I'm using Wordpress, Drag and Drop 1.9, H5P 1.7.9, on desktop (chrome). Settings attached.

Any ideas?

Many thanks :)
