When I started here at MH, the smart matching was working real well. I just had a few matchings. Then I changed the settings because I wanted some matchings. At first I had some more. But the last weeks it become redicules. It started to grow with a couple of hundred new matchings per day. Then I tried to change it back to exact matchings. And today I had 2500 more matchings. How do I get rid of all this faulse or not visible matchings?
