Error on Traffic Shaper 0% Bandwidth

[Pavan 1]

Hi everyone,

Backstory:
recently we migrated from pfSense 2.4.x to 2.7.2 which was a direct update. Everything worked fine etc the traffic shaping feature.

Following is the error:
There were error(s) loading the rules: pfctl: the sum of the child
bandwidth (1200000000) higher than parent "root_igc4" (1000000000) -
The line in question reads [0]: @ 2024-01-31 16:45:05

Following is our configuration:
Name → FAIRQ_7
Priority→ 7
Scheduler Option → Random Early detection in and out
Bandwidth → None

Add new Queue(Default)
Enable
Name → qFAIRQ_2(Default)
Priority→ 2
Scheduler Option → Default
Bandwidth → None

Add new Queue(ACK)
Enable
Name → qACK_6
Priority→ 6
Scheduler Option → Random Early detection in and out
Bandwidth → None

According to the configuration the Bandwidth on Queue(ACK) should be 0% which was migrated off from 2.4.x but on 2.7.2 it's not letting us save 0% bandwidth for some reason.

And due to this new rules which are created are not taking effect it's only after we disable and enable the Traffic Shaper completely the rule is effective.

Any help would be very helpful.
Thanks,
