XG-7100 1U : Issue when changing interface assignnments

[MATHEMATIC]

Hi Pfsense community,

Started using pfsense 2.4.4-RELEASE-p3 with an Netgate XG-7100
I have setup an LACP LAGG which uses those two ports (ix0 and ix1).
when we try to delete interface or change interface assignement, i'm getting every 15 minutes :

ix0: Interface stopped DISTRIBUTING, possible flapping
ix1: Interface stopped DISTRIBUTING, possible flapping

One time, when I tried to reboot, the netgate has detected a crash report or programming bug.

Thanks in advanced,

Regards
