There’s some that you’ve listed that I don’t believe actually exist, such as the splash level 2 extended potions. I’ve marked those with Grey in the spreadsheet.
According to the creative mode inventory, they exist. under the brewing tab at the bottom
According to the minecraft wiki:
This class of potions exist in the game code and are functional, but cannot be brewed. This seems to exist primarily as potions that have both an extended mode and empowered mode, but the brewing process normally only allows for one of the two to take precedence
