### assignment type spurious warnings

I have recently composed a problem set from three other problem sets in order to compose a proctored gateway test.

Firstly I exported all the questions from the relevant set to a .def file I then imported these into another problem set whereupon I deleted all but the questions that i wanted in the proctored gateway test. I then changed the assignment type in the homework sets editor and performed a run through of the test to check timing etc

I decided that there were too many questions in the proctored gateway test. For ease of editing i again switched the assignment type back to problem set but now on each question i get the following warning messages

Any idea what might be causing this?
