DBMS_LOGSTDBY.INSTANTIATE_TABLE returns "ORA-20001 fixing up the name in the impdp stat table"

One of our clients had the above problem, just after applying a patch to our product's schema, and now I've been able to reproduce it on a local database. In my test I have a Primary and Logical Standby both running on my Windows desktop on EE 12.1.0.2.0. I've recently recreated the Standby and it has been working correctly after making changes to the Primary, I've switched log files and seen V$LOGSTDBY_PROGRESS is up to date as it should be.

As SYS on the Standby with logical apply not running...

CREATE PUBLIC DATABASE LINK PRIM CONNECT TO SYSTEM IDENTIFIED BY <pass> USING 'PRIM';
