Closing Physical Count

I have updated and printed the variance sheet; I am trying to clear the frozen items, but it tells me. . ."IM2 I/M Inventory Item Whse Detail is in use by another task". There is no one else in this program, why won't it let me clear? (Reason for asking: I am trying to delete an item that I have just set up and when trying to delete it tells me that I cannot delete during a physical count)

Any help will be appreciated! Thank you.
