Symptoms

Getting error "Invalid 'Table' selected on the List record. The 'Task Observable' table is in application 'Threat Core', but the current application is 'Security Incident'." while modifying list layout under Observable in SIR

Cause

It is working as expected. It is a platform limitation across scope. The only way to configure the column is the gear icon. 

Resolution

1) Switch to Security Incident scope 
2) Go to https://<InstanceName>.service-now.com/nav_to.do?uri=sys_ui_list.do?sys_id=54b33da10b0222002e64a3e337673ab6
