in my sandbox i have a custom object(vessel__c) with custom fields (Project_codeword__c,vessel_name__c). case is using a lookup field on this object. When I create a new case and start typing, suggestions appear with the first two fields from my search layout. Here I can search for both the Project Codeword and the Vessel Name and get the correct records displayed.
But when I do inline edit in an existing record, I get no results for the vesselname only for the codeword. Is this a bug or is there a setting somewhere else for this behavior? Here is a screenshot for better understanding.
