NVH analysis in OptiStruct with data setting in HyperMesh

I am making this example on a reluktance motor i have already created on flux motor and exported to Flux 2d , then I made a CAD for the stator to make the mesh on Hypermesh for making the Data support . The problem showed up when i was making the forces date collection, the collection support isn`t showing the data support which i created and i can´t creat a new forces data collection .
i want to know why is that happening although i´m going step by step as the example is showing .
