Emergency Exit Window Leaking (Already Replaced Butyl)

I replaced the butyl tape and re-caulked the window a few days ago. I was out today with the hose checking for leaks and I found a significant one. While spraying down the exterior of the window it appears that I'm getting quite a bit of water on the inside. It's coming from the seal of the emergency window and the frame of the window (since this one is removable). The seal has a split in it (see pic) where they originally taped it and that's where the water is coming in.

Is the window made to be removed and reinstalled? Can you take it out and replace that weather stripping? Any ideas on a fix would be great. Thanks
