Hi Skyper,
I have adjusted the tagging information regarding the sidewalks present on each side of the roads in the changeset 135745782 referring the details on the wiki https://wiki.openstreetmap.org/wiki/Key:sidewalk. 
We apologize that editor failed to adjust the attributes correctly in the first instance, feedback has been provided to ensure that the attributes are rightly tagged while making modifications on the existing segments. 
Regards,
Deepikja
