You cannot make changes to any fields in Enterprise Search / Global Search in Edit Master Layout.
SAP Hybris Cloud for Customer
Reproducing the Issue
1. Click the Global Search icon and type in your search terms.
2. Switch to Adaptation Mode by clicking the Adapt menu > Edit Master Layout option.
3. Edit Fields in Results of the Global Search.
NOTE: If you remove/hide one of the standard fields from the master layout of a view for example, Tickets field Status - the Enterprise Search will still display this field and display results based on that field value.
As the Global Search is a Custom Control, adaptations are not possible. This is the expected system behavior.
