Hello and welcome to OSM,

thank you for you contributions!

I stumbled across this change in this way:
https://www.openstreetmap.org/way/128573470#map=17/-37.214135/-72.386105

You tagged it with cycleway:left:oneway= -1 and cycleway:right:oneway=-1.

Could you please describe your motivation why you choose this tagging? 

This tag combination does not make much sense. See https://wiki.openstreetmap.org/wiki/Key:cycleway:right:oneway

I want to understand how it came that you  being a person new to OSM choose it such that we eventually can improve the description in our wiki.

I think that both these tags can be safely deleted.
