company name in invoice address field missing

Hello,

in the form where clients enter their invoice address I am missing the field for the company name. There is only first name and last name of the person, but no company name.

In my dashboard I only can activate first name and company name for the invoice address, but company name does not seem to be an option (see attachment).

How can I make sure that clients can enter their company name into the invoice address?

Many thanks in advance
Birgit
