Wrong IPv6 prefix delegation on multiple PPP profiles

Hello,
I’ve setup router with IPv6 subnet and 2 PPP profiles.
First profile is setup to delegate IPv6 subnet (profile named “l2tp”), second one is not setup to delegate IPv6 subnet (profile named “vpn_static”), but when client with profile “vpn_static” requests subnet via dhcp it’s getting pool from first profile.
Configuration from IPv6 server router

[admin@ipv6-router] > /ipv6 pool export

software id =

/ipv6 pool
add name=pool_hetzner64 prefix=2a01:4f8:1c1c:5af::/64 prefix-length=127
[admin@ipv6-router] > /ppp export
