Sorting To Subfolders - naming with year token

My question concerns the name of subfolders when using "Sort into subfolders".
In the initial conditions I'm intending to capture the year from the file name. This appears to work correctly but when I add the sort into subfolders with the intention of naming the new subfolders with the year what I get is the current full date - thus instead of 2015 I get 2015-04-08.
Am I writing my rule incorrectly or is something else amiss?
Thanks.
