Is this because it's type is 'None'? I'll open a bug, but I would also
like to be able to fix this myself, I just don't have an idea where.

Using filters currently is not an option, since I want to parse the
output of multiple fields automatically. With filters I would have to
run multiple instances of tshark AFAIK.
