Maybe, maybe not... Are you sitting back on the wide part of the saddle? Sitting on it more toward the nose might cause issues even if the seat has a groove/split. What used to work for me (before I went completely recumbent) was to angle the nose up just a half a hair. That was enough to stop me from sliding forward onto the nose as I rode. Otherwise, I had The Problem(tm).

My old favorite saddle used to be an Avocet Touring II, which had little raised bumps under my sitz bones, for a bit more padding there and nowhere else. Probably the precursor to the current 'ergonomic' saddles.
