blf extension after pick up

Hello everyone, and I apologize in advance of my English.
I find myself with this problem.
S50 with a fw and phone Yealink T27p I programmed the keys as blf extension (that work well).
with an incoming call to the group, if you make a pickup, the group of the ring phones stop ringing but blf keys will continue to flash.
(Pickup is working properly)
What could it be?
