Master/slave (clone) resources cannot go into groups, IIRC.
You need to have the group depend on the clone being in master state.
Here's a CIB idiom for doing this:

I haven't tested this, and it's more than possible you can't do all this
with the GUI. But, you should be able to create the master/slave
resource and the group just fine.
