TinyFPGA BX Pin 18 and 20 not working


While in bootloader mode my TinyFPGA BX’s general purpose pins have a voltage except on pins 18 and 20. After programing and holding all the pins high in code, pins 18 and 20 still do not have a voltage. Is there something special about these pins, or is it likely they are zapped out? I am using the pin configuration from the provided APIO template.
