Cat3850 MPLS PortChannel issue

Hello, i have a some strange issue.

 

I have Cat3850 will connected to other switch with PortChanel1(trunk all) and PortChanel2(trunk all) to another switch.

From po1 i got 2 vlans 10,20 and from po2 got vlan 30

 

Config of vlan intf:

 int vlan 10 

    ip addr 10.10.10.1 255.255.255.252

    mpls ip

 

int vlan 20

   no ip address

   xconnect vfi 20

 

int vlan 30

   ip address 10.30.30.1 255.255.255.252

   mpls ip

 

When mpls traffic goes from vlan 30(po2), thats work perfectly, xconnect work, when mpls traffic goes from vlan 10 on po1 and then they must be return to po1 in 20 vlan, it not work, xconnect status UP, i see remote mac on 3850 in sh mac add vlan 20, but they dont send it through po1.  Maybe i'm dont known something?
