cannot install Data Miner repository on 23c

getting the following error when trying to install Data Miner repository

section 1 : error returned

section 2 : script been run

section 3: two rows are returned when I run the follow subset off the script. I think this is causing the issue

==================section 1
ORA-01422: exact fetch returned more than the requested number of rows
ORA-06512: at line 4
01422. 00000 - "exact fetch returns more than requested number of rows"
*Cause: The number specified in exact fetch is less than the rows returned.
*Action: Rewrite the query or change number of rows requested
