Routing for notifications defaults to last option

I’m using Gravity forms for several websites and I’m encountering a peculiar problem on one of the sites I’m maintaining. I’m sending notifications using routing, usually this all works well but for one form all the routing options I’m setting are defaulting to the last possible option of the field that contains all the options.

Thus I can select as much ‘contains’ options I want, after saving they’re all the same, thus the notifications are (usually) failing because that condition is hardly ever met.

What am I missing?

I recommend opening a support ticket for this issue if you have not already:
