Does anyone know around supplemental logging data in GoldenGate 19c?

Hi

I found some strange(?) behaviours while using "supplemental logging" feature in GoldenGate 19c.

If anyone knows the reason (or, any hint of the reason), please let me know.

I used a command "add trandata <pdb>.<user name>.<table name>", then this table was registered in the "ALL_CAPTURE_PREPARED_TABLES" table.

Next, I used a command "delete trandata <pdb>.<user name>.<table name>", but still this table remained in the "ALL_CAPTURE_PREPARED_TABLES" table.

And also, I got a schema information of "<pdb>.<user name>" by a command "info schematrandata <pdb>.<user name>", though I never used the command "add schematrandata <pdb>.<user name>" before...
