I'm seeing a lot of confusion around the Suggestions report lately. People are "making changes", but the suggestions are not going away. (see this Facebook post )
Here's how the Suggestions Report works...
Every week, all WikiTree profiles are scanned, looking for various types of "errors", mistakes, discrepancies or other inconsistencies to be corrected.
If you make a change, and mark it as Corrected, then the next time the report runs, it will look again and see if the change really corrected the error or not. If it was not the expected change, then the suggestion will still appear on the report the next week as well.
Just because you make some change, doesn't mean you've actually corrected the actual suggestion. You need to understand what exactly is being suggested and make that change. (click on the green question mark for the specific suggestion for the help page with more specifics about what is expected)
If you didn't make any change (because one is not needed), and only mark it as a Comment, then again the report will continue to report it. "Comments" are only for us humans, and are ignored by the reporting tool.
If no change is warranted (because the unusual spelling is correct, or the date mismatch is correct, or whatever other issue it might be), then you need to mark it as a False suggestion to remove it from the report. Then this specific error will never be checked again on this profile.
Do not mark is as False, if you made no corrections, and there should be a correction to make.
The other options (including Comment), Not corrected or Proposed merge, are meant to leave it on the report as a reminder, each week that there is still work to do here on this profile. It serves as a reminder to anyone else looking at the same report that someone else is also working on the problem (based on whatever comment is left)
The Suggestions Report is a growing and evolving tool. Almost every week, new types of errors are added to the scan. So, just because you've cleared all your suggestions this week, next week there might be a new type of error suggestion to correct. Not all of these suggestions are warranted, but the only way to know for sure, is to have a human look at each one (and mark it appropriately).
Hope this helps (I'm sure I've left something out by mistake).
