Do I have the right type of account for teams?

First, I really do love BitWarden. It works! But, one thing is confusing to me: I upgraded to Premium so that I could share with team members. But, it seems that team members are not viewing the same structure. For example, I have a collection called “EPA” - Karen is a member of the team, and Karen has access to the EPA collection. But, I don’t think she can save new passwords to the EPA collection. Is that true? If so, what kind of account do I need so that it works better?
