News Page pulls from all aggregator categories

I have installed News Page onto two different websites. On each site, the module pulls feed items from all of the aggregator categories -- not just the selected aggregatory category. The word filtering seems okay, but all sources are pulled, which makes for quite a mess.

I cannot imagine what might be wrong on my end. AFAIK, I have the aggregator set up properly, with several feeds for each aggregator category. There are no errors in the logs. I checked for the obvious things, like an extra line or space at the end of the php file.

Any ideas?
