GUI Error from older version of GUI

I am updating an existing gui. I copied the .m and .fig files of the original gui and I made sure that the saved file name was changed. I was able to run my version of the gui but have recently been getting error from the original gui after making more updates. I tried to change the tag names of the radiobuttons that were called to error, attempting to minimize the possible connection between the 2 gui's. Right now, the old gui pops up as a subgui to the updated one whenever those radiobuttons are operated. I tried running the subgui in coordination with the main updated gui but more errors (reference to nonexistent fields) appear in the command window.

I'm not sure how to possible break the connection between the 2 guis so that each one can run separately from the other.

I appreciate your time and help in advance.

When running the new gui, I continue to get errors from the original gui even if I ignore the subgui that shows up.
