Project wrongly appears under the "Self" Category

Project wrongly appears under self "Self" category on actors page - When they were not playing themselves. I have applied what is laid out in this article (linked below), which suggests adding "reenactment" to the tile. However I am finding IMDB rejects it? any help much appreciated! title page: https://www.imdb.com/title/tt12280960/ https://help.imdb.com/article/contribution/filmography-credits/why-do-some-acting-credits-show-up-in-a-separate-list-under-a-category-called-self-even-if-those-people-didn-t-actually-appear-as-themselves/G5H28P735WRDPSKN?ref_=helpsrall#
