Gold Tone String Question

All,

I recently purchased a Gold Tone CC-OT and the site lists the strings as: GDGBD - .010, .013, .016, .024w, .010

but they only sell the following strings. What gives here?  This makes zero sense to me.   Why in the world would they not sell the strings they put on the banjos they sell?  I think I want to go to light strings  Is it fine just to make the switch or would a setup be required?:

Light Strings:  .009  .022w  .013  .011  .009

Medium Strings: .011  .024w  .016  .013  .011
