Did you install the patcher hotfix on the DSR file page? I think it's more for Unofficial Skyrim Patch problems but it might fix your problem plus you need it anyway.
I've installed Dual Sheath Redux by following GamerPoets video. He suggests rerunning the DSR patch each time I change my load order. Is unchecking a mod in the right pane but leaving it checked in the left pane considered changing my load order?
