question about gpio pins

I cant get certain gpios (39,35) to get input on my beaglebone black.

I was able to get pins 44 and 48 to show a change in input so I dont think its an issue with the board.

Here is some info relating to how the pins are set up right now when I checked the pins.

pin 44 (PIN44) 10:gpio-64-95 44e108b0 00000008 pinctrl-single

pin 48 (PIN48) 14:gpio-64-95 44e108c0 00000008 pinctrl-single

pin 39 (PIN39) 5:gpio-64-95 44e1089c 00000037 pinctrl-single

pin 35 (PIN35) 1:gpio-64-95 44e1088c 00000027 pinctrl-single

I dont understand these values mean exactly, I was under the impression that the 0x08 value meant that this pin isnt even in gpio mode and something like 0x37 and 0x27 meant that it should be in gpio mode.

All the bit meanings can be found in the TRM, but also here:

What does this mean?
