Alias ID in brackets in subject line

[zaptax]

Hey, Previously in workspace, If i made three "alias ID" - sales, billing, invoice in a particular ID and say I receive a mail to sales@xyz.com, The mail used to be visible as [Sales] - Subject Line,

Similarly, if I get a mail to billing@xyz.com, the mail used to be visible as [Billing] - Subject line

This helped me differentiate which mail belonged to sales, which belonged to Invoice and which belonged to Billing.

I can't see this feature anymore. Am I missing it or how do I enable it? Pls help
