Export Not Loading Pre-sets

Hi, since the update, previously created pre-sets for exporting files are failing to load. If they do load, they have alternative settings eg NTSC 30 rather than pal 50 for an MXF export that was previously fine. You then have to load numerous false settings eg DnxHD to get rid of the NTSC which wont move, then go back in and load the preset. Very frustrating. Thanks.
