Email Parser not detecting modules

I'm trying to set up the Email parser, but when I get to the "Create New Parser" box the module I want to create the Parser in is not shown.

I changed the name of my Deal's module to Allocations/Booking (as I'm using it to manage current and new bookings). However in the Create New Parser screen the only module it's showing is "Bookings draft".
From what I can tell this is a module I created weeks ago that I've since deleted.

How can I get the Parser to update to the current modules I'm working on?
