Hello Ahmad-0772,       
Thank you for your edit and removing the duplicate nodes, but Please next time when you remove the duplicate, please check if some of them has valid data that will be entirely removed if you did not copy them to the node that you wanted to keep.               
See this example, the one you removed had name:ar and name:en: 
https://www.openstreetmap.org/node/10980198505/history          
And the one you kept is without those names:    
https://www.openstreetmap.org/node/9221331912/history             
No worries, I will copy them to the current kept one, but just wanted to share this info.              
Regards.
