GE frig water valve

I am trying to use a 1/4 compression nut with sleeve to insert to refrigerator connection only, the sleeve keeps getting in the way, if i take it out the hose will come right off. Manual says 1/4 compression nut and sleeve, doesnt mention size so i bought the same size as the connection.
The sleeve won’t fit into the GE connector. Thanks in advance.

Sorry, correct model #: gfss6kkxss
