Limiters ECN input validation problem
You create limiters with ECN.
Then you decide to remove ECN and so remove ECN checkbox.
Limiter should be updated but its not.
/rc.filter_configure_sync: The command '/sbin/ipfw /tmp/rules.limiter' returned exit code '65', the output was 'Line 4: unrecognised option ``noecn'''
So coding error somwhere, but it would be great if this was fixed before 2.4.5 hits the release.

I can't reproduce that error here.
It works fine if your selected QMA and scheduler support it from what I can tell.
For example, a quick test:
: cat /tmp/rules.limiter pipe 1 config bw 1000Kb codel target 5ms interval 100ms noecn sched 1 config pipe 1 type fq_codel target 5ms interval 100ms quantum 1514 limit 10240 flows 1024 noecn : ipfw /tmp/rules.limiter :
(No errors in output)
If anything it looks like you found a combination of settings that input validation should reject, but it isn't.
We'll need to know exactly what is set in the GUI when it works/doesn't work and see the contents of your /tmp/rules.limiter.
Too late for 2.4.5.

RED/GRED limiters do not have noecn option, https://www.freebsd.org/cgi/man.cgi?ipfw(8):
red | gred w_q/min_th/max_th/max_p [ecn] Make use of the RED (Random Early Detection) queue management algorithm. w_q and max_p are floating point numbers between 0 and 1 (inclusive), while min_th and max_th are integer numbers specify- ing thresholds for queue management (thresholds are computed in bytes if the queue has been defined in bytes, in slots otherwise). The two parameters can also be of the same value if needed. The dummynet also supports the gentle RED variant (gred) and ECN (Ex- plicit Congestion Notification) as optional. Three sysctl(8) vari- ables can be used to control the RED behaviour...
