How to remove the Identity Correlation from Identity Now UI?

Hi All,
I am trying to remove the Identity Correlation from the Sailpoint Identity Now UI but i am not able to do that.

Even if I am trying to do with the API i.e., update Source Partial (PATCH Operation) it is removing in the response content i.e., null but at the UI side, it is still there.

Can anyone help me with the procedure?

I’m not sure that a null value is valid for correlation on a source. Admittedly, I’ve never tried to do it though. But what’s the use case? Why would you want to do this? Even if your source is an authoritative source I’d think you’d at least want to correlate the account ID attribute to the identity name attribute (or whatever makes sense in your case).
