Alert in my pfsense

[Nemesis-f]

Hello Everyone,

Since some day i have some error in my pfsense. I don't know why but some alerts appears :

Filter Reload
There were error(s) loading the rules: pfctl: the sum of the child bandwidth higher than parent "root_re2" - The line in question reads [0]: @ 2019-09-02 10:45:00

Error occurred
SHAPER: no default queue specified for interface opt1. The interface queue will be enforced as default. @ 2019-09-02 10:47:48

I think it's an error with queue but i don't know where is the problem. I follow this tuto (sorry it's in french) :
https://www.provya.net/?d=2015/02/04/19/23/48-pfsense-configurer-la-priorisation-de-trafic-avec-cbq

Here you can find some of my configuration :
Traffic shapper by interface (FREE interface is diseable)

Here my floating rules, it's strange but state stay at 0/0B, my rules don't work ?

And here my statues queues :

I don't know if i give you enough information, but thank you all for your help and have a good day.
