Lee Pro 1000 Sensor clip

[hp246]

Hoping someone can help me cause Lee sure can't.  I have a Lee Pro 1000 set up for .45 Colt.  Because I double check each round for proper powder drop (Have had problems with this before), I only send one case around at a time.  I have a primer loading onto the primer pin, even when a case does not activate the sensor.  This causes primer to flip out of the primer slot all over my loading bench.  I called Lee, and the best they can tell me is that I should watch the video on their web site.  I install the sensor clip exactly as shown, and the problem persists.  If I flip the sensor clip around backwards, it keeps the primer pin from going down far enough to load a primer on the pin.  Any thoughts would be appreciated!

(Except spending money on a new Dillion.  Just getting started and bought 3 guns, can't exactly ask my wife for permission to buy a new reloader.)
