Remove Reward Store Rewards?
You can also do this with cheats if you don't want or can't use this mod.
You need to type
traits.remove_trait [trait_codename]
The codename is the name of the trait.
So for example if you want to remove the markatable trait you have to type in the cheat
traits.remove_trait trait_Marketable
A more detailed explanation and a list of the traits can be found here

Edit: I am not quite sure if the second link works as intended. If you follow the first link, go to Non-Pack Filtered Visible Traits en then to Reward Store traits you should find the list.
All credit for this list goes to EgonVM . No point in typing it all out again if this simmer already provided such a complete an helpful overview.
