Wireshark-dev: [Wireshark-dev] How is the protocol display filter name determined?

Hi,
 
I have a custom plugin building with the Wireshark 2.0.2 source on Windows 7, using cmake.
 
For the most part the plugin works correctly.
 
Display filters on particular items appear to work.
 
However, when I try to use just the protocol name to filter I don't get any packets.
But if I clear the display filter the packets are there.
 
The protocol is called FAPI.
 
This is used to register the protocol.
 
    proto_fapi = proto_register_protocol("FAPI", "FAPI", "fapi");
 
The packets come on a particular UDP port.
 
If I start a capture I can see the packets and the PROTOCOL column says FAPI.
 
When I enter "fapi" in the display filter field and hit apply everything disappears.
 
A display filter likes this:
 
fapi.FAPI_subFrameIndication_st.sf
 
works correctly.
 
Any ideas on where I should look?
I've tried rebuilding everything from scratch but end up with the same results.
 
Thank you
