Cannot see type list when creating metainputs

[asd2012]

Hi,
I have been trying to work with custom types. I follow the steps to create a user defined feature and when comes the time to associate a type to my metainputs, the selection is completely blank.

I've tried everything, my pathway as been properly specified in the options menu, I enabled all the packages and CATIA even recognizes the types when conducting a search. The selection should not be blank and should show all the types available. I'm at a loss and that is why I turn to forums.

Any help is appreciated.
Thank you.

Could you post some pictures or if possible the part? By the way, custom types and meta input are two different things working with udf, how are you going to use them both?
