Hi Barry,
I've just tested on my setup running PD 2309.
I used different bunches of surface and scuba stuff which always show up white balance changes well. I used both 720 mp4 and 1080 mov clips from different cameras.
When I first started, I thought I'd replicated your fail but I've done it 10 times so far, closing and starting PD in between on 5 tests and using both the white balance picker and the colour temperature and hue sliders and it seems to apply to all correctly.
I can also deselect the white balance on a single clip and apply to all properly, so all clips become deselected.
We'll see what others have to say?
Cheers
Adrian
