IE Data models vs Information model types

Hi there,

I came across an unusual query today whilst attempting to add an information model type to our current customised method filter.  When it came to the connection types selection, there were no options in the box on the right hand side of the wizard function.  It becomes more complex.  We already have IE Data models on our method filter, but when I unselected them (In test environment) I was then allowed to choose the connection types for the information model.  Visa versa occurs.  If I first select the information model, and then the IE Data models, I am then not given the option to choose the connection types for the IE Data models.  I have never come across anything like this before and hope someone can help me.
