It’s working the way it’s intended to work.
Before this update this is the way it WAS working.
The 7.22. and earlier logic was checking to see if the current rating is less than the selected filter rating. So if you choose to filter 1 star, and you come across an application with 4 stars, the logic would read (if 4 < 1 then skip). So in this case, nothing was skipped.
There were 3 ways we could have gone with this and the one we selected is this: show all applications that equal selected star filter, only.
You may also want to ensure you have cache cleared on your hosting platform as well as your browser. This was tested very extensive and has worked in the manner described above.
