Routing filters rule vpnv4 route filtering failed with "dst"

RouterOS Forwarding Protocols

On RR , I wana change some vpnv4 routes community Filter by prefix

In /routing/route , I can print detail by where dst-address in 100.64.0.0/16

[admin@LAB6-R1] /routing/route> pr detail where dst-address in 100.64.0.0/16
Flags: X - DISABLED, F - FILTERED, U - UNREACHABLE, A - ACTIVE; 
c - CONNECT, s - STATIC, r - RIP, b - BGP, n - BGP-NET, o - OSPF, i - ISIS, d - DHCP, v - VPN, m - MODEM, a - LDP-ADDRESS, l - LDP-MAPPING, g - SLAA>
H - HW-OFFLOADED; + - ECMP, B - BLACKHOLE 
 Ab   afi=vpnv4 contribution=active dst-address=100.64.2.100/32&2:100 routing-table=main label=16 gateway=1.1.1.2 immediate-gw=10.21.0.2%vlan21 
       distance=200 scope=40 target-scope=30 belongs-to="bgp-VPNv4-1.1.1.2" 
       bgp.session=bgp1-1-to-2-1 .ext-communities=rt:1:100 .local-pref=100 .origin=incomplete 
       debug.fwp-ptr=0x20342180

But when i add filter rule by "dst in 100.64.0.0/16" , it doesn't work

if (afi vpnv4 && dst-len == 32 && dst in 100.64.0.0/16){append bgp-ext-communities  rt:1:600;accept }

we can find the detail about vpnv4 route "dst-address=100.64.2.100/32&2:100" , it add "&RD" info , that maybe the key.

but why it can be matched by "dst-address in 100.64.0.0/16" when print , and can not be matched by routing-filter, This confuses me a lot , What is the correct operation

try other ways , all doesn't work

if (afi vpnv4 && dst-len == 32 && dst == 100.64.3.200){append bgp-ext-communities  rt:1:600;accept }
if (afi vpnv4 && dst-len == 32 && dst == 100.64.3.200/32){append bgp-ext-communities  rt:1:600;accept }
if (afi vpnv4 && dst-len == 32 && dst in 100.64.3.0/24){append bgp-ext-communities  rt:1:600;accept }
if (afi vpnv4 && dst-len == 32 && dst in 100.64.3.200/32){append bgp-ext-communities  rt:1:600;accept }

but remove dst ,it can work well

if (afi vpnv4 && dst-len == 32 ){append bgp-ext-communities  rt:1:600;accept }

 Ab   afi=vpnv4 contribution=active dst-address=100.64.2.100/32&2:100 routing-table=main label=16 gateway=1.1.1.2 immediate-gw=10.21.0.2%vlan21 
       distance=200 scope=40 target-scope=30 belongs-to="bgp-VPNv4-1.1.1.2" 
       bgp.session=bgp1-1-to-2-1 .ext-communities=rt:1:100,rt:1:600 .local-pref=100 .origin=incomplete 
       debug.fwp-ptr=0x20342180

so how to match route by dst
