Hello

I am using Mikrotik version 6, currently I have activated a /48 range through BGP and added it to Networks, my internet provider has given a /128 range and announced to set it on Vlan with a special name and IP Set them on the system, for example:
2a06:xxxx :yyyy ::54/125 is set on the created vlan
And inside the route IP version 6, I set a route to ::/0 to the IP announced by the data center, which is the following IP:
2a06:xxxx :yyyy ::51
I have divided my range 48 in Mikrotik into several ranges 64, for example:
2a0f:XXX :1::/48
And now it is set as follows:
2a0f:XXXX :1::1/64
2a0f:XXX :1:1::1/64
2a0f:XXX :1:2::1/64
But now, when I try to take a trace from Mikrotik, it sees the gateway, but then it doesn't go to any other destination.
And if Trace is sent from outside to Mikrotik, the connection is received with the IP above my hand and not from Mikrotik!
And if for example IP
I set 2a0f:XXX :1:2::2/64 on a virtual machine, the trace received from outside is such that the address 2a06:xxxx :yyyy ::54 is received, but the rest does not return.
And if I directly trace the ip 2a0f:XXX :1:2::1/64 it shows my upstream ip

It should be mentioned that in the Neighbor tab, I don't see any local IP that I want to connect to
