Change default folder for storage of new presets

I shoot a lot of weddings and create a set a presets for each wedding which I store in a new folder. Lately when I create a new preset, Lightroom changes the folder location back to "user presets", requiring me to change it back to the folder that I created for that wedding. It seems like in previous versions of Lightroom (I am using 5 now) that it would just default to whatever the last used folder was. Anyone have any tips on how to return it to using the previously used folder, rather than going back to "user presets" everytime?

Thanks so much!
