Bugs in content types

Creating content in Moodle 3.1 plugin.

Desktop, Chrome, not sure how to check H5P plugin version, H5P Columns - drag and drop.

Hi,

A member of staff has developed a column interaction which at one stage was successfully reporting a single score to the Moodle gradebook. After more content was added it has stopped providing a score altogether.

I have been through it in detail and cannot see anything obvious. Do you have any suggestions as to what might be stopping the score output working in a previously working column? Would it be possible to porvide you with h5p file to look at?

Thanks

Nick
