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

    Simple,

    Dump the 555.

    Get a 12F683.

    Then use ...
    Code:
    HPWM  1,2,20000
    No external parts. No difficult calculations.

    If desired, add a serial port to set the output with your computer, save the values in EEPROM, then disconnect the computer.

    Can't do that with a 555.
