Hi muralito, Thank you for reaching out.
The Maproulette instruction was to split the geometry at node 1759328137 which I separated, the others were additional edits in the area.
I removed the one-way tag initially, but then I realized there wasn’t any source to confirm if it was a roundabout or a circular junction. When I reverted my changes, the one-way tag returned. 
Based on available sources, I still think that it should be a junction=circular tag instead of a roundabout because we cannot confirm the presence of yield/give-way sign or related road markings. 
Please let me know of your opinion on this matter.
