I am using the default Bliz Target frame but using the addon for target of target and target of target target. Now getting an error:

This results in the default target frame not showing if I enter combat before targeting something.

When I join a raid the Main Tank windows don't show up though there are players with the role set as tank.

How do I get the Main Tank windows to fill?
