SgNBAdditionRequest [Malformed Packet] V2.6.4

Using Wireshark 2.6.4, the X2AP SgNBAdditionRequest and subsequent SgNBAdditionRequestAcknowledge show Malformed packet and looks like Wireshark not able to dissect 5G NR messages yet...

When can wireshark support 5G NR X2AP messages (NSA3.x)? is there a workaround for this
