Using makepassive function for passivity correction

I am trying to convert a non-passive touchstone file to a passive one using makepasive function and the code is as follow
S1 = sparameters('Sample_file.s2p');
ispassive(S1)
ans = 0;
S2 = makepassive(S1);
ispassive(S2)
ans = 1;
rfwrite(S2,'NewTouchstone.s2p');
S= sparameters('NewTouchstone.s2p')
ispassive(S2)
ans =0;
I believe the makepassive function converts all the parameters to passive ones and i also get a logical 1 after the conversion.
But after I write it into a touhstone file and do the passivity check again, it fails.
Can somebody help me to understand what might be going wrong.

I forgot to attach the touchstone file. I could not attach the snp format and hence have attached the text format, just change the extension to snp while downloading it.
