Departure screens at Waterloo

I normally catch the 17.05 or 17.35 Waterloo to Weymouth services. Both of these are formed of 2 class 444 units, and they divide at Southampton, the front part going to Weymouth and the rear part to Poole. However, quite often the departure screens on the platform at Waterloo show some ridiculous formations, eg, front 4 coaches for Weymouth, middle coach for Southampton Central, and rear 5 for Poole. This has been going on for months - or possibly years - and clearly confuses those who are not regular travellers. You shouldn't be telling your passengers nonsense! When is this going to be fixed!
