I have a multi-company set up with 4 main companies (with no parent company) -

Company 1, Company 2, Company 3 and Company 4.

I have a multicompany user, user 2 who should be able to transact with all the four companies. I have added all the companies as allowed companies for the user and also allowed the user to access multicompany. However, the companies are not appearing in the company field in documents eg invoices. I can however see the companies in the dropdown if I log in as the default admin user. Could this be a bug?
