You are wrong and you know it. You can't proof your version.

It can be proved fairly easily and quickly that the episodes are not part of any season because the FOX website only has 11 episodes and Disney+ doesn't even show "O C'mon All Ye Faithful" or "The Past and Furious" as part of season 36, at least in the US; they're listed in their own season titled "Exclusives." Season 36 isn't even on Disney+ in the US either, unless you also subscribe to Hulu. And even then, season 36 has its own, separate listing because it's an in-season show that's part of the Hulu catalog.

There are two broadcaster now(Fox an Disney+), an both must be used as source.

Incorrect. FOX is still the main and only network that airs regular episodes in the US.

Fox has only their episodes on site, because they didn't have rights for Disney+ episodes.

Correct, because they didn't air on FOX and didn't air as regular episodes, so they're not regular episodes.

In overall order Disney episodes are 10/11 an 14 in season. You can't ignore this.

It can be ignored because you're incorrect, at least in the US. Disney+ doesn't even show "O C'mon All Ye Faithful" or "The Past and Furious" as part of season 36, they're listed in their own season titled "Exclusives."

Secondary sources are pretty good in such case. For example - https://tv.apple.com/us/show/the-simpsons/umc.cmc.1kfo3z1jtaj8ff6wsh9cvxbwu. This is official and reliable source and can and be used here. They released episodes officially.

Secondary sources are irrelevant for this since it's pretty obvious that FOX does not consider "O C'mon All Ye Faithful" or "The Past and Furious" to be regular episodes because they didn't air them.

Now there are two main network - Fox and Disney. Both episodes are regulars. Only information about this episodes was that they will air exclusively on Disney+. In all sources about this episodes was said - "Season 36 four episodes will exclusively air on Disney+"
