I'm using the standard Case object that has a custom field called: Case Financial Vendor which is a lookup relationship to the standard Account Object.
When trying to use Quick Text for merging fields from the related Account (or Case Financial Vendor), it won't merge anything or show any data.
This is the quick text and merge fields I'm using:
The merge field {!Case.Claim_Financial_Vendor__c} is working as expected, but then the ones with the __r are not. The fields are completed in the Account object so that's not the problem, they have data.
