The created "figure" is not a "file". "Files" are found on the hard disk, not on the screen, while "figures" are the windows on the screen. Although you can store the contents of a figure to a file in the ".fig" format on the harddisk, you cannot "close" such a file.
I guess, you want to check if a figure with this name is open already. Then exist() is not sufficient, but:
existingFig = findobj(get(0), 'Children', 'flat', 'Name', 'Selected Image'); close(existingFig); % Or "delete()"
If no existing figure is found, existingFig is the empty matrix and close() does not perform anything.
I tried running the same thing and it worked, however, I assume that your main problem is in the if statement, not the close line.
Run the script in debugger and see if it's actually going through the if statement. Look up how the exist() outputs work because 1 is not always the output. I would suggest changing it to something like
if exist('Selected Image', 'file')~=0 close 'Selected Image' end
