Mameshiba x Nanatsu no Taizai Collab CM - It's worth noting that I think the official upload was private before it was eventually approved on MAL.
Regarding Mirai e no Tegami, it may not have been changed because it is following the original release with 1 video = 1 episode (this is also how AniDB documents it).
These are the two episodes:
ep. 1: https://www.youtube.com/watch?v=8GEv8rQt3h4 (Feb 15, 2016)
ep. 2: https://www.youtube.com/watch?v=OenHb_5mgAI (Mar 6, 2017)
ep. 1 then had individual videos released for each of the segments on Mar 29, 2016 (eps. 1-10 in your list). I'm not going to claim that the database is 100% consistent on if segments released together are counted as one or multiple episodes, but at least you can follow the reasoning for why it is documented this way.
Battle Mode - Full version is 1:16 (https://myanimelist.net/forum/?goto=post&topicid=1926141&id=63685586)
JAA Meets Yokohama - Previously was accounting for a single segment by Furukawa (Akai Kutsu! Onnanoko!)
Japonese - Full version is 6 min. (https://asifa.jp/member/renzo-kinoshita.html)
Katei Sekken - The YouTube video title says it's an excerpt.
Mameshiba x Nanatsu no Taizai Collab CM - It's possible you did see the correct video before it went private, but read Mizore's edit to be sure: https://myanimelist.net/forum/?topicid=1820854
Ookina Furudokei - This is considered to be lost. You probably meant to mark Ookina Furudokei (2002)
Some resources to keep track of entry updates:
https://anime.plus/ArcadiaInferno (Especially helpful for manga, which HoF does not track. Note: Sometimes the data is a little stale, so you'll need to wait for a refresh on their backend before the mismatches drop off.)
https://anime.jhiday.net/hof/user/ArcadiaInferno#errors (for episode changes)
https://anime.jhiday.net/hof/history/series (Follow this to keep up with data changes. Note: This does not track duration updates, which is why notification is so important.)
If you come across any duration updates, errors on my list, or any anime entries in the DB that need updating, please do let me know.
