Default S-health and S-voice won't update?

Hello everyone,

So i have towel rooted the S5, it's great and works fine except for a couple things. Like the title says, neither s-voice or s-health update. They both keep telling me they have updates but, when I try to update the app force closes. Unfortunately "blank" has stopped. I was wondering is this because of towel root or another reason. Any help would be appreciated.

Thanks
