Issue with EVPN local switching

I have  this topology in our network. 

Customer1 = NCS1- NCS2= CUstomer2. 

Between  NCS1 and NCS2  we have EVPN.  Customer 1 connected to NCS1 witch single active, but Customer 2  connected to the NCS1 and NCS2 via all-active through  switch. 

NCS-1

l2vpn bridge group EVPN_GIST bridge-domain GIST_858
l2vpn bridge group EVPN_GIST bridge-domain GIST_858 mtu 9180
l2vpn bridge group EVPN_GIST bridge-domain GIST_858 interface Bundle-Ether4.858
l2vpn bridge group EVPN_GIST bridge-domain GIST_858 interface Bundle-Ether15.858
l2vpn bridge group EVPN_GIST bridge-domain GIST_858 interface Bundle-Ether15.858 split-horizon group

Sometimes this topology don`t work. On the Bridge domain we can not see  mac-address our customer. If i delete bridge  domain and create this bridge domain again, our NCS learn mac address.

Anybody have this problem ?
