Strange, it appears that WINRED might be doing the same thing. I think I donated once or twice back in 19/20, and it has 17 different amounts (some as small as 1.42) that it shows I made. None to ACTBLUE, though.
I have tried out one called Tusk Search https://tusksearch.com/ but haven't switched over to it completely. It lets you choose between left/center/right results supposedly. Just haven't taken the time to test it out so can't vouch for its veracity. YMMV
