Did you use it in the coop or the run? If in the run and it turned to mud, you might need to use from larger particles like large flake shavings, bark mulch, twigs and pine needles and then add dry on top of the wet to keep a balance. In the wet seasons, the run litter is going to get wet but if it's muddy, then it needs to go deeper..much deeper.
If in the coop, same thing...you need more dry materials if you have a lot of water coming into your coop..but it shouldn't stay wet all the time if you have a sheltered coop. This winter when it got so cold as to freeze the litter, it was the first time I smelled poop also but I think it was because the litter couldn't compost at those temps and the poop was not being digested well by the litter. It was very brief and as soon as the subzero temps left, the smells went away.
Go deeper on your DL and you'll see better results, especially when it's a really wet season.
