Using View/Hide Columns in Mapping screen causes program to go back to Map your Data

[RDmitchell]

Problem
When you have mapped your data and you are in the Mapping screen where you can see the actual data with it's new mapping (the list view), if you click the View/Hide Columns button, and select new or deselect existing fields, when you click Save Settings, you are put back into the very first mapping screen, and when you move from that screen to the final mapping screen, the list settings that you changed were not saved

To reproduce

• Import a data file and map it
• After clicking Map Your data, you will be put into the Mapping screen where you can see the actual data with the new mappings
• Click on the View/Hide Columns button
  
• You will see the Building List Settings dialog box
  
• Deselect a checked field (or select a new field) and click Save Settings
  
• Program puts up the "Please wait while your data is loaded"
  
• And then it displays the first Mapping screen
  
• So you have to click the Map Your Data button to get back to where you started (which is where the program should have put you in the first place after Save Settings)
• And it didn't save the setting change -- in this example I deselected State Province, but it is still displayed in the list

I am closing this issue because @nicholasserra discovered that the functionality of the View/Hide button in Mapping isn't working. For now we are going to remove the View/Hide button since it doesn't work properly, and make a new issue to add it back with proper functionality
