Thanks for your answer, John - our big problem turned out to be that in the assignment settings, file submission type had PoodLL checked by default for all assignments. When we unchecked PoodLL as a file submission type, the problem went away for new submissions. (PoodLL was a new choice with our recent upgrade. The administrator was able to change that default.)
I believe sometimes files will still be marked as draft for some unknown reason. Since the files are actually uploaded and there, it's only a bother because they say draft. Also there is no notice that there are files submitted that need grading. Instructors have to view the assignments and sort by submission date to find the ungraded assignments.
