These four scripts can override or reset the auto-rating behaviour:
The Clear... scripts change the default 0% rating which allows auto-rating into a 1% rating which shows as no stars.
The Reset... scripts change the 1% value back to the default of 0% allowing auto-rating to take place again.
None of the scripts will change other manually set values, which will be 20%, 40%, 60%, 80% or 100% for one to five stars respectively.
Your screenshot fails to display album rating alongside rating. Doing so should make it clearer what is going on. As noted earlier:
"In addition I believe iTunes may sometimes transfer auto ratings from a device into real ratings in iTunes."
It might not be the auto rated albums that are causing you a problem so much as manually rated albums that you don't want to be rated. As before:
... unrated/zero rated tracks gain an auto rating if there is an album rating, and unrated/zero rated albums gain an auto rating based on any rated tracks. (Specifically the mean average of rated tracks from the album.)
