Because you have TUs in your TM than use these fields you cannot simply remove them (at least Trados Studio will assume this is the case).  So you need to export your TM to TMX, and then create a new TM with the fields and attributes you want to use (that should match the ones you use already), and then import the TMX into your new TM.
