In mp3tag v.3.27a, I can no longer enter track numbers in format xx/xx e.g. 04/10.  
I used to be able to enter track numbers of the type XX/XX e.g. 04/10, but in the update to mp3tag v.3.27a, I can no longer do this.  
I have tried using the auto-numbering wizard, tried entering a leading zero to the digit e.g. 04, but nothing works for me.  
It used to happen automatically- I just used to enter my track field with the format xx/xx e.g. 04/10 without any problems, but I can't do it since the update to mp3tag v.3.27a.

Any simple suggestions please?

MP4 tags do not allow a leading zero.  
So what kind of files are these?

My music files are .mp3 or .m4a

The MP3 ones should work, the m4a ones won't get a leading zero.  
... provided that you have more than 9 tracks to renumber.
