That narrow curved panel between the end panel with the airbag switch and the rubber door seal is probably not fixed in properly, it has a fixing at the bottom that fits over and into the trim piece below it, I’d bet that bit is not inserted properly, and is therefor distorting the shape, with the dash end panel removed you can pull the narrow trim piece out, take a look and see if it can be realigned.
I've looked this morning, the panel isnt broken, but it seems so flimsy and is only clipped in at one end, the rest of the fitment seems to rely on it fitting in behind the door seal and 'just fitting' into the plastic above, nothing connects it to the air bag panel to keep those together and looking good. I've improved the look but will probably resort to some duck tape to try and improve it further.
Thanks for the suggestion
