Need help understanding why more than one date for same country

After googling "all the presidents' pets episode air dates", chose to look at 
https://www.episodate.com/tv-show/dogs-101-cats-101?season=1
which shows

Notice this site has these at ep 11 & 12, while IMDb has only the one, at ep 9.
My analysis stops here, because I'm not actually that interested; just wanted to see what google would find.

I know few people will care, so I'll start with I believe there was an original episode that was then updated&renamed when Obama got his dog, but that it's the same ep with content added.

For those that like details
I think the original ep was the "Presidential Dogs"(PD) that bderoes found and aired in 1/09. I then think they updated it once the Obama's got their dog (April 09), and guessing changed the name to "All the Presidents' Pets"(ATPP) and re-released it in 7/09.

I found a Discover Asia press release that has the PD title (which doesn't mention Obama) but does not have the ATPP title.  That press release description as well as 5 other places I could find an ATPP description all have the exact same description as Presidential Dogs with a sentence added about Obama. Also there is no place where you can stream the PD title; they all have the ATPP title only.

I also just happen to have the ep recorded and re-watched it. Unfortunately about half the credits are missing that might give a bit of a solid clue/answer.  In any case, nothing that probably can be done to the imdb page, but there are some things that just bug you after you step in it.

Sounds likely, especially since "The first inauguration of Barack Obama as the 44th President of the United States took place on Tuesday, January 20, 2009." And the first air date is 17Jan.
Notice the series/episode is on Amazon Video (with air date in July):

All this story seems to be mysterious when searching in the web archive :))

The PRESIDENTIAL DOGS was announced for JAN 17, but post-factum is absent in schedule. And later the DOGS 101 marathon was scheduled, that finished with All the President's Pets at 10PM.
