Removing dual years from tag panel to single year

If you record, let,s say an album, using Audacity, and you fill out all the info and save then bring it into MP3Tag you will find you have dual years in the year panel, something like 1981\1981. If I remember correctly there is a way of correcting this but I forget how, been a while since I used MP3Tag. Can anyone help me with this? Thanks in advance.
