Hello Md Razzakuzzaman Palash,

You’ve recently added some duplicate data using GeoMapTool.

osm.org/way/479936025 is an example of this.

Please don’t use it, it’s very very broken.

If you’d like more information, please email the Data Working Group via data@osmfoundation.org.

After reading this message you’ll be able to continue editing, but please don’t use GeoMapTool.

Best Regards,

Andy Townsend, on behalf of OpenStreetMap’s Data Working Group.
