Autocompletion not autocompleting fully?

OS: OSX

Description:
I'm not sure if this particular to Visual studio code or the plugin itself. But whenever I start write assert I get the autocomplete for the following two items assert_eq and assert, If I select assert_eq and press tab I get the correct autocomplete that looks like this assert_eq!(, );

However if I start writing eq I also get the autocomplete for assert_eq, but when I press tab in this case it only completes to assert_eq nothing else. Ideally it would autocomplete in the same way as above.
