The issue is most noticeable in enwiki.

Go to RC page and select to highlight (without not selecting filters) all 'Contribution quality prediction filters' - Very likely good, May have problems, Likely have problems, and Very likely have problems.

There will be changes that are not highlighted, e.g.

@jmatazzoni here: Just to clarify @Etonkovidova's points above: the following screenshot shows me filtering for human-created page edits to articles. All such edits should get ORES scores. But when I apply one color for each of the four ORES Quality categories, many edits still don't have colors. This should be impossible, since the ORES Quality categories cover all possible scores, from 0 to 100.

I made a similar test with the User Intent filters, with similar results. See screenshot.
