I've found a lot of errors on my suggestions list, where the error is the tombstone or the Find A Grave memorial. There's no correcting those on the WikiTree side. I've tried, but no matter what I do, the suggestions keep popping up.
For example, I can't help it that my great-great grandfather Ledford's tombstone is incorrect; here's his actual death date per contemporary records, with an accompanying explanation under Research Notes. Do the WT bots care? Nope. They just keep suggesting a correction.
It's frustrating on the best of days.
