MXR M87 Gain and Reduction Light No turning On

Good morning,

Just hoping someone could help me out. I just bought an MXR M87 compressor pedal and for some reason everything seems to be working expect the gain and reduction light does not turn on.

I have tried turning the ratio all the way up. I turned the volume of my bass up as well and nothing. I put up the attack and still nothing.

When I turn on the pedal the lights turn on, then they turn off.
