ID: #1,197,211,245 Captured soul but secondary pantehon not active

I did use a divine vessel inside a map to capture Merveil, which would give me access to the secondary pantheon for Soul of the Brine King.

Inside the map, I first killed the boss and then entered the mirage.
When i finished my map, 2 full divine vessels were thrown at my inventory. When I tried to deliver them to Sin in act10, both dissapeared but my secondary pantheon never activated.

Capture the soul of this boss again to re-enable this secondary pantheon.
