UK 50 pence 2011 kayak/canoeing. 2 different KM#'s

Just noticed that a 2011 Olympic 50 pence coin has been added with catalogue number of KM#1182.
There is already a similar coin KM#1168.
Can someone please explain difference.

KM# 1182 is correct.
KM# 1168 is Athletics (which Numista says is KM# 1150).

I hope someone else can confirm, before the referee amends pages.

That page is for the scarce (only 19,751 minted) original Athletics coin, dated 2009 with KM# 1150. The same coin, dated 2011 like all other Olympic ones, is KM# 1168.
The coin for Canoeing is KM# 1182.

That page has wrong dates and images, I think. Should only be 2009 on there - even though it matches the NGC link above. Surely there are no 2011 coins with KM# 1150 number?

Zac,
According to the Numista website, kayak coin is listed as KM#1168

Yes, I know - my reply agrees that it is incorrect.

Zac,
Just checked my 2013 Krause catalogue and the coin is indeed listed twice. As KM #1168 and KM#1182
Very strange?

Agreed, strange. Also the 2011 Athletics coin is on NGC twice.
KM# 1150 I think should only be used for the 2009 coin; then the 2011 coin should be KM# 1168.
Neither of those are the Canoeing coin which is KM# 1182.

Summary:
KM# 1150 Athletics (2009) https://en.numista.com/catalogue/pieces16651.html
KM# 1168 Athletics (2011) [need separate page creating]
KM# 1182 Canoeing https://en.numista.com/catalogue/pieces18211.html
Can the referee confirm those and then amend/create please?! Namely amend Canoeing to KM# 1182, and create KM# 1168 page using images and members from 2011 line on 2009 page.

Shame it is night-time here now; can only take these quick pictures ...

Will take better ones tomorrow to put on the 2009 page.

Thank you Zac for helping out and trying to get to the bottom of this mess. We are trying to rationalise the listings but this is a real challenge since we base our catalogue on the KM structure and numbering system and as we well know Krause is flawed and has many mistakes. This is a case in point. I was looking into it earlier since a member drew it to my attention and when I went on Numismaster.com and separately entered the KM references 1168 and 1182, they both came up with the same results. So I really don't know what the answer is and sadly I am unable to move members collections but if there is any other way I can help then please let me know.

Why should the Athletics coin need two separate entries?
As the coin is exactly the same, except the date, surely one entry covers both
