Autoload Filament Stuck in Unload/Load Loop

Hello,

For the longest time my printer wouldn't Autoload filament. Today I decided to fix that issue. I updated the firmware, and that didn't help. The Support->Sensor Info was giving me a 1 constantly like there was filament in, even if there wasn't any. So I followed the directions in the guidebook by first making sure the cables were seated correctly (they were), then I tested out the sensor itself after blowing compressed air on it to get rid of dust. It read 0 after that, but when I put it back in its place, it'd read 1. I cleaned out the small area where it sat as there were a few small hairs, still 1. I looked into the forums and found that some people had to shave the lever down just a hair because of heat expansion. That seemed to work. Seated it read 0, and when I put filament in it read 1.

But now I have another problem. It autoloads just fine now, which is great. But when I start to print it's caught in this loop of having me unload and reload the filament over and over. It's currently reading 0 like there's no filament in it, even though there is filament in it. I can't even Unload Filament because it thinks there is none after canceling the print. I have turned the printer off and back on again with no improvement.

Can someone help me with this issue?

In some Mk3S printers the Filament sensor is not in a suitable place to consistantly work properly, 
Sometised all you need is a thin printed washer under the sensor PCB, within the extruder housing
