PTPv2 Malformed Packet (Exception occurred)

When capturing the traffic from a PTP GM I have under test on CentOS I get this error on all "Announce Messages"

Expert Info (Error/Malformed): Malformed Packet (Exception occurred)

When I run the same capture on a Windows 10 Machine I have no error. If I save the file captured on Windows and open it on CentOS the error is present.

This leads me to think that theres is something different between the PTP protocol is decoded(??) on a Linux system compared to a Windows System.

Anyone have any thoughts?
