Element Duplication (Overlapped)

hello

I faced with the problem while I organized from component 1 into component 2 , I duplicated  elements in component 1, I think, It will be easier when I want to edit this element later.

After that, I found out that many elements is added at the same location (Node), that meant, in displayed, we see 1 element but actually, it is overlapped.

How can I fix the problem instead of delete and create it again.

Thank you for your answer

Best regards
