Please just ignore them.

First one should came from the "lo" device; it does not have
EUI-64 identifier.

The senario of the second one should be:
  1) We should send MLD Report message when joining a group 
     other than the link-local scope all-node multicast address.
  2) At first, when an interface going up, a link-local address is 
     automatically generated and assigned on the device.
  3) When doing DAD for an address including the link-local address, 
     we must join solicited multicast address for it.
  4) Kernel trys to send a MLD message for the solicited multicast address, 
     but it does not have any appropriate source (link-local scope) 
     address at this moment.  Kernel complains about it.
