Hi, Need a little help please.
I understand Hyperfocal distance but I cannot understand the ML output numbers.
Example. at 24mm F11 I get Focus dist: infty,  DOF near 2.6m,  DOF Far: Infty Hyperfocal: 2.6m,  so I am assuming that focus should be made at the 2.6m mark in the scene if this is correct then the DOF near should be 1.3m to Infnty as Hyperfocal distance is normally half the focus distance. 
Sorry if this sounds kind of UGH!!

But you are not focused at the hyperfocal distance, you are focused at infinity!

If you are focused at infinity then by definition, the DOF near = hyperfocal distance, DOF far = infinity * 2 (aka infinity). If you are focused at the hyperfocal distance, then DOF near = 1/2 hyperfocal distance and DOF far = infinity.
