Cant assign multiple /64 from /48 pool

Running RouterOS 7.1rc4 on a CCR1009-8G-1S-1S+. I set up a DHCP Client to request a /48 Pool from my Provider. Now I want to provide a /64 from this Pool to two VLAN's. But the system tells me that the Pool is exhausted after the first /64 assignement. Did I do something wrong?

Thanks @hzdrro @netravnen, this was the issue! It now works.
Another question: The device now creates addresses in the format XXXX:XXXX:d80b::1, XXXX:XXXX:d80b:1::1, XXXX:XXXX:d80b:2::1 and so on. Is it possible to set this number myself? e.g. to get XXXX:XXXX:d80b:50::1 on VLAN50?
