Mikrotik ipsec SPI mismatch with multiple subnets

When you have multiple subnets in ipsec tunel and you can see bad SPI for given subnet like this (pinging to 10.49.41.0/24 subnet, which has eroute #97, but incoming ESP has SPI from eroute #96:

[root@router.ista.cz ipsec.d]# ip xfrm monitor | grep 109.238
        src 109.238.209.50 dst 178.17.0.241  reqid 0x4095 protocol esp  SPI 0x3d282872
        src 109.238.209.50 dst 178.17.0.241  reqid 0x4095 protocol esp  SPI 0x3d282872

[root@router.ista.cz ipsec.d]# ipsec auto --status | grep praha | grep 3d282872

[root@router.ista.cz ipsec.d]# ipsec auto --status | grep praha
000 "praha/1x0": 10.49.41.0/24===178.17.0.241<178.17.0.241>...109.238.209.50<109.238.209.50>===10.49.224.40/29; erouted; eroute owner: #97

You have to set level to "unique" instead default "require", see screenshot
