it says "January 12, 2014 1h 30m" !?

I've noticed that 'be off by a day' problem too. Something seems to be going wrong? It could be that this has recently been linked to the time zone in the profile settings. I'm afraid this will result in a bunch of incorrect entries.

This episode of Sherlock premiered on 12/1/2014 and not 11/1/2014.

I have take a look at this entry and the 3 episodes are correctly listed as January 1st, January 5 and January 12, and, looking at the changes history, the dates haven't been changed since the 2016 year.

Note : I have hide your 2 other reports. One report is enough for the 3 episodes.

It says only "January 12, 2014".

"1h 30m" displayed below is the duration of the episode and is not related to the date.

Well true, I just copied everything. For me it's the same as in your picture.

Sorry about filing so many reports. When I go on the edit page the air dates listed are for the day before the initial broadcast (so on Letterboxd “The Empty Hearse” is displayed as premiering in 2013).

The Letterboxd entry for "The Empty Hearse" doesn't link to this series, but to a wrong movie entry that has been deleted sometimes ago. You will have to contact the Letterboxd support team for this.
