Duplicate member keys

[kimmal]

Getting the following error when publishing a new cube. 

XQE-ROL-0016 More than one member was found in [AType].[AClass].[PType] with member key values [Engine]. Member [Engine] could already have a parent of [], or there might be duplicate member keys. Duplicate member key values for different level keys may occur if an insufficient number of level key columns are defined in each level during modeling. This requires a fix to the model.

When I browse it in Cognos Cube Designer, it looks the way that I think it should look but I get the above error.

I've attached what I see when I browse Members, which is what I'd like to see (although I still need an additional level in there for Aircraft Code).  Also in the bmp is how I defined my levels

Any help is appreciated.  New to Dynamic cubes, but have used and modelled something similar in FM

Please disregard, I think I got it.  And there was the almost exact same question asked already.  My bad, I thought I had done a proper search before I posted my question.
