HELP! Depreciation "Type of Asset" all imported as blank

I just noticed that ALL of my depreciated "Type of Asset" entries on all of my schedule E rentals are BLANK! They all had valid entries last year. So I started a new return, imported from last year again, and the "Type of Asset" fields are all still blank! Furthermore, when I try to select an asset type, I get only two options: M - Home Office and N - Home Office Improvement. What's going on?
