Unified Audit logs reporting errors on shrink space and create global temporary table wri$xxxx

After enabling unified auditing on our Oracle 12.2 databases on Red Hat linux we are seeing errors in our production databases for "shrink space" and and "create global temporary table wri$xxxx"

ORA-955 is returned on "create global temporary table wri$xxxx" - I found an Oracle doc - 2065012.1 (Audit Trail Update Table Program Failed with Error 'ORA-00955: name is already used by an existing object'), but it is referring to Oracle Application Object Library - Version 12.1.3 to 12.1.3 [Release 12.1] 

ORA-10655 on Alter Index shrink space, Doc ID 18193833.8 refers to 11 and says the issue is fixed in 12.2.

ORA-10636 on Alter Table shrink space - According to Oracle Support
