Are you confirming the report or claiming it's a duplicate?

jiingy Well I can confirm the bug, but it relates to MC-269936.
This bug describes behaviour in the world list menu, whereas MC-269936 describes behaviour in the resourcepack and datapack menus. This is not a duplicate however it does relate.
Can confirm, this relates to MC-269936.
Please note there is no need to make a report about the same bug with the same resource pack when you can provide the bug about this resource pack in 1 report, which in this case is MC-269936.
