We could call it Earth-200000 or whatever you want (I don't know how exactly all those universes get their designation numbers) but those stories are not part of the MCU. The numbers are generally assigned within handbooks. If a number has not yet been officially assigned then the marvel wiki uses a TRN (Temporary Reality Number), for example "Earth-TRN001", Earth-TRN002, etc.

Hope this explanation helps. As for these stories, yeah, sounds like it contradicts the established canon.
