Draggables Are superimposed by the Drop zone

Hi 

I created a drag and drop educational material and it was working fine until i exported the H5P content to share it with a friend. 

Now the draggables disappear behind the drop zones when I drag them. Some drop zones keep disappearing in view mode. The (select drop zone) option keeps deselecting some drop zones on its own.

All these bugs appear in view mode and in Blackboard, where I embedded the content.

I use the web version on Chrome to create and edit.

This is happening in the two drag-and-drop content items I created. 

I am attaching one of them. 

Solutions I have tried that did not work: 

• Changed the layer order
• Changed the background opacity 
• Created a copy of the drop zone 
• Created a new drop zone. 
• Downloaded the H5P and tried the desktop version; the desktop version could not open the file. 

This is how it looks in view mode where I dragged the image, and now it is behind the drop zone 

I appreciate the help
