Unmenu.awk errors

Hi all, this is my first unraid build and it was going swimmingly until a couple of weeks ago when unmenu became unreachable, I had a look through the logs and found the following errors repeating over and over:

Line 1223

============================================

This error seems to repeat until I tell it to "killall awk". I have tried correcting these syntax errors manually by editing the unmenu.awk file but when the server is restarted it just comes up with more syntax errors further down the script. I have also tried deleting unmenu.awk and restarting the server, when it comes back up, the file has been recreated with the same syntax errors.

I am using a standard HP microserver n54L with one additional 2.5" drive in the ODD space as cache. Any help would be appreciated.
