Support for omittable field

Hello,

I've noticed that the field/fieldEn is mandatory and can't be omitted, I think it would be great, if these would get omitted if field is unspecified. I had trouble finding anyone who specifies their field in their works, at least in the latest year. Usually only programme is specified. Including screens, just so the difference is clear. I have no clue what is my field, I believe the correct way is to just omit it.

This is how it looks like with no changes to the styles

This one is omitted, as it should be in my case
