Custom Settings Issues

I was trying to create and utilize Custom Settings for my Skuid page.

I have a picklist field that I wanted to have two subsquent currency fields that would populate values based on the selection of the controlling picklist field.

The problem I am having was I noticed when I initially created my Custom Setting in Salesforce I accidentally created the setting as Private List. When it needed to be Public according to posts I read on the Skuid Community. 

So, I tried to edit the existing setting to change it from Private to Public. But it wouldn’t let me, so I decided to delete the whole Custom Setting and create a new one. Now when I try and create the new List and Public setting and link it to the same Custom Object I had previously created one with it says “Error: That object name is already in use.” Even though I have know other Custom Settings using that object, and have hard erased it from the deleted objects section of the Custom Settings area.

Anyone know who I can create a new Custom Setting related to this same Custom Object? Also,
what is the process of implementing it into my scenario with the picklist and dependent currency fields once I am able to hopefully create the new Custom Setting?

Are there any alternatives in Skuid to creating a Custom Setting to accomplish what I am trying to do?
