I interpret your first 2 images as showing a very slight amount of front focus. The front 6 and 8 on the right look sharper than the back 6 and 8. They ought to be at least the same, or the back even a tiny bit sharper. The latter if the usual rule that DOF extends further to the back than the front is visible on the ruler.
