Can't go back in to edit a PowerPivot table

[deeznutz206]

Whenever I create a new PowerPivot table and then want to go back and edit the fields in it, it won't let me go back to the Design Wizard(where I can just drag and drop the fields that I want). It just takes me back to some sort of text commands. This only happens on my laptop. However, if I send the file to someone else and ask them to create a PowerPivot table and send it back to me, I then am able to go into the Design Wizard for that table and do the edits that I want. Hope that makes sense.
Is there some sort of setting on my laptop that is preventing me to be able to go into the Design Wizard to do edits on the table that I created? It is very inconvenient to have to send someone a file and ask them to create a simple PowerPivot table and then send it back to me just so that I can go back in and do the edits. This is just so strange and my manager doesn't know what is going on either.
