Routine cast correction according to IMDb guidelines rejected twice

A routine correction, made according to IMDb cast guidleines in Wild Zero (1999) was rejected first as a part of extended edit (#220827-205611-879000) and then on its own (#220828-201019-908000). It is a change of "Self" listings which I do often, because at one point in IMDb's history person portraying themselves could have been listed as "Self" but then rules were changed to make "Self" restricted (very nearly exclusively) to non-fiction portryalas, while all other cases should be accordinglly listed as acting, with name repeated in the role field. A lot of the remants of previous rule variant are still there to be discovered and whenever I see that I correct that according to IMDb guidelines. Both times edit was rejected as "Unable to Verify". I am really puzzled as to what person/algorithm who rejected it was unable to verify, exactly. IMDb's own rules?..
