G-EUPG missing air vents in row 6 both sides. Is this common for these 319 / 19B configurations with convertible seats?

I managed to bag 1st Y row C seat last Friday, which was 6C, but felt (only a little bit) uncomfortable due to no air vents (had a brisk walk from North Lounge to gate 15 to ensure I could make use of priority boarding to avoid any ohc issues, which there were when the rest boarded).

Doing a daytrip to London this Saturday to make up for missing points to requalify as Silver (and of course to visit yet another part of the lovely city). 'Premium' Y seating for both out and back opened up this afternoon, so I put myself in first row Y again, 6A... need to weigh the shoulder space comfort versus the air vent situation. (assuming the curtain does not move anymore, I know, I will check regularly)
