Hi, Well perhaps port registration automatically is done for UDP and TCP or the one doing the registration Registered for TCP as well in case it would be used later or ...
But regardles, any thing sent on a port number that is used by a Wireshark dissector(not hueristic) will be dissected as that protocol Regardless of what it actually is. A workaround is to dissable that protocol.

[...] The UDP Destination Port number for GTP-C request messages is 2123. It is the registered port number for GTP-C. The UDP Destination Port number for GTP-U request messages is 2152. It is the registered port number for GTP-U." Which one is more credible?
