If I am understanding your drawing you have helper address on vlan 20 and 30. But these vlans are configured to learn their addresses from DHCP. So they would send a request to the broadcast address. They are not able to forward to the helper address till they have an address.
Having looked again at the post I see another significant problem. The router has configured only one DHCP scope as far as I can tell. That scope works for the subnet connecting R1 and R2 on the Ethernet. I do not see any scope configured for vlan 20 or for 30. Each vlan needs its own subnet and its won DHCP scope.
I now see that before posting the question in this form that the original poster also posted the same question in the LAN forum. I suggest that any further discussion be focused on the LAN forum which is where it started.
