Single post in PokéWalker Adjustments

I am struggling with my retreaving my Pokemon from my Pokewalker. Since I had to use points my Pawmo is ready to evolve since I have enough points to evolve it on the Pokewalker, but when I do it says I have stuff in my Pokewalker invitory that I need to get in order to finish evolving and getting my Pokemon from the Pokewalker. But when I look I have nothing to retreave in order to get my Pokemon out of the Pokewalker. And if it is different from the items in my Pokewalker invintory then where is the Pokewalker invintory so I can remove whatever is in my Pokewalker invintory so I can get my Pokemon evolved. Please help.
