I don't use radius for DHCP. Try
/ip dhcp-server
set X use-radius=no

you don't use radius but i want to use radius)) and i need answer please help.

I use radius, just not for dhcp. I can tho. Do you have radius logging enabled?
/system logging
add topics=radius action=memory

For dhcp, User manager should only return Access-Accept and the ip address (Framed-IP-Address for FreeRADIUS users) or the ip pool (Framed-Pool) when the mac address is sent. You can only return attributes that apply to dhcp. No Mikrotik-Group or anything like that.

Take a look at the wiki. It shows what you can send with Access-Accept.
