Export from PL 10 and some files are a pixel or two larger in dimension from same original dimension

I am having issues with PS10 and exporting images. It seems to be exporting some pictures in a different dimension even though they are all the same dimensions in the originals.

They are taken in 6192x4128 and show as this in the image browser. However on export it seems to export some in this original dimension but then some at 6193x4128.

I have not done nay resize or cropping on the images and its from a focus stack so they all need to be the same, and I cant see why it would change some.

I have tried various extensions and they all do the same
