Emulated message is somehow different

Hello!
I’m using two esp32dev with two CC1101 a remote and a receiver (kitchen fan).

I’m able to read the remote:

home/desk_rf/433toMQTT/8/32763    {"value":32763,"protocol":8,"length":16,"delay":384,"tre_state":"-","binary":"0111111111111011","raw":"13817,308,317,615,642,299,639,317,633,315,625,312,618,320,630,323,633,311,621,325,626,298,631,313,648,301,626,319,311,619,651,308,619,","mhz":433.92}
home/kitchen_rf/433toMQTT/8/32763 {"value":32763,"protocol":8,"length":16,"delay":383,"tre_state":"-","binary":"0111111111111011","raw":"13835,326,323,617,623,319,634,305,648,306,621,320,630,318,631,309,622,327,612,322,631,309,624,325,628,294,633,334,298,641,620,320,633,","mhz":433.92}

So I try to emulate the command from kitchen_rf to desk_rf (and the kitchen fan)
But the emulation of this “button” even if received correctly from desk_rf seems not correct to the kitchen fan itself. As the KF does notthing:

#EMUL
home/desk_rf/433toMQTT/8/32763    {"value":32763,"protocol":8,"length":16,"delay":383,"tre_state":"-","binary":"0111111111111011","raw":"13830,385,427,724,794,367,771,389,767,408,733,420,771,366,769,390,773,366,790,355,775,396,768,391,766,392,748,413,362,781,773,367,795,","mhz":433.92}
mosquitto_pub -t home/kitchen_rf/commands/MQTTto433 -m '{"value":32763,"protocol":8,"length":16,"delay":383, "repeat":5}'
# Note  I've tried changing delay from 380 to 390

I’ve tried every other protocol but the remote seems to appear only on 433RF.
Any suggestion?
