ACL not imported for <str>

  Explanation:  The ACL contained in the RBR  file  could  not  be
  imported to the named object (database/relation/field)

  User Action:  If you really want it, you must either obtain  the
  needed  privileges  (BYPASS)  or  import  the database under the
  account of  the  former  owner  (which  may  not  be  sufficient
  anyway).    If   you  do  not  care  about  the  restoration  of
  protections you can ignore the message or  import  the  database
  using  the  NOACL  parameter which will cause all privileges and
  protections in the RBR file to be ignored.
