Hi again Anita
I was able to reproduce this with Foundation 12, when you open a script directly from Foundation in Studio, even after you save it locally.
Instead, if you go to the Transaction scripts folder, find your script, right click and download to your PC (aka save link as)

and then open the locally saved script in Studio, the Workspace will show all of the tables and allow you to modify your field selection.

It's a bit round about, but it will allow you to modify the script without having to recreate it.
FYI
