I cannot reproduce your issue: by setting the "Dissect T-PDU as None" GTP
preference, I do get the T-PDU data payload displayed with 3.4.2. If I let
the default value (TPDU Heuristic) it properly identifies the payload as IP.
So it could be related to your GTP-U PDU where the heuristic fails for
example. Please check the behavior if you sendure to set the preference to
None and share the packet if it still fails.

Best regards.
