    why not using Shiftin/Shiftout who give you the choice to choose those pin you want?

    The Edward suggestion is also good if you don't need any pins for PWM or interrupts.

    LCDOUT and SHIFTIN/SHIFTOUT don't use any internal ressource, software based only.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
