The Flow Graph on ver1.12.1 can not display L2 message such as EAP.

Hi! Now I am using v1.12.1 wireshark on my laptop PC(windows 7). And I am going to analyse the 802.1x. So, I have tried the "Flow Graph" to check the sequence of 802.1x by the "standard src/dst addr". However, the "Flow Graph" can not display EAP messages. While, the "Flow Graph" displays the RADIUS messages. I suspect the "Flow Graph" in v1.12.1 of wireshark has above bugs. Because, the "Flow Graph" in v1.10.7 of wireshark can display EAP messages with the same procedure.

Please give me the solution of above problem.
