Can't delete items from the on page grader

[CommT]

I check every single box and they don't delete. This is driving me nuts. Please can you delete them for me because I am not impressed with this AT ALL.

In fact I am getting so cross I am in danger of screaming hysterically which might get me the sack and it would be all your fault.

That was slightly tongue in cheek, but please can you fix it please. please.

Sorry, ignore this - seems asking the question works! It has now finally deleted everything,

I wonder if there is a bug though because surely it shouldn't be that bloody difficult to delete something?
