Adding a "company" to a cast list?

I've tried to add this credit to the IMDb a couple of times, but it's been rejected. (Last addition number: #221115-204310-885000)

Basically there's a sketch show on the BBC that always has as the cast "Pace Theatre Company". Now, I don't think it's right to add it as "other company", because it's always listed among the featured performers. But it keeps getting rejected.

It can be seen on Youtube: https://youtu.be/A9ORnTHOnOg?t=1681
