68 of the “known problems” seem to be the red color of links. The 
color (#ba2710) is tested against the background color of the body 
element (#555753). If we would use the links directly on that color, 
that would indeed fail WCAG2.0 but the link color is always used against 
white or other suitable colors, which [meet the contrast ratio][1] just 
fine.

The first error (<input type="submit" alt="submit" value="submit">) 
looks like a copy & paste error, and while it is not optimal it should 
not create problems with assistive technologies. I have noted the error 
and we will correct it with the next update.

Both tests show errors for the empty th element in the top-left of the 
table, and while a td would be more appropriate, it should not cause 
confusion in practice. We will take the feedback in condideration for 
the next update.

For more information on best practices, find the tables tutorial here:

https://www.w3.org/WAI/tutorials/tables/

and the example with two headers specifically here:

For more information on evaluation tools, see [“Selecting Web 
Accessibility Evaluation Tools”][2]. We also have a [list of 
evaluation tools][3] that allows you to search for an evaluation tool 
that suits your needs.

Best, Eric
