I am trying to create a ‘Location directive actions’ line for ‘Only fixed locations’ and enable ‘Allow negative inventory’ but don't know for which reason system is not allowing me to remove or update one specific range in edit query window that is "No open quantities". I need to remove this range from edit query window. Can anyone help me with this?

I want to remove below highlighted condition but the "Remove" button is disabled as i am not able to remove it.

Below is the Finance and Operations version that i am using.
Installed product version : 10.0.10
Installed platform version : Update34
