Why have I stopped getting points for uploaded files?

I uploaded 3 files a couple weeks ago. The three files combined have been downloaded 153 times.  Ive only received points (I checked my points log) for 81 downloads.

One pattern has been downloaded three more times and Ive received no points.

I havent had any trouble yet getting my points.  Maybe you have duplciates
