Windscreen Seal R53

I was just changing my windscreen wipers and I noticed that the windscreen seal in the bottom middle of the screen, where the seal joins. I can lift the seal off on the glass, only ever so slightly but enough so water would go down the back of it, also where the metal trim joins over the top of the seal, I can push this with my fingers and it gives 1 or 2 mm or so.

Can anyone let me know if this is normal, possibly by looking at your own car?
