Because you `write()` the whole text four times to the file.  Make the 4
replacements first and rebind `text` to the string with the replacements
each time, and *then* write the result *once* to the file.

text = text.replace("Left_RefAddr", "FromLeft")
text = text.replace("Left_NonRefAddr", "ToLeft")
# ...
file.write(text)
file.close()
