Hi, as the title indicates I have an issue where copying more than one element results in duplicates being pasted. This issue does not occur when copying only one element at a time, I have checked that the existing elements are not already duplicated (including the cleanup tool).
Version: MicroStation CONNECT Edition 10.15.2.11
I did see this issue was mentioned once or twice a few years ago, I've included a video demonstrating the issue, zip as well incase it doesn't play.

I know this is a very old post, but this exact process can also happen if you have a reference attached of the same document with the 'Locate' option turned on. Selecting an element normally will select the actual element, but clicking and dragging will select all elements in the range, including the reference. You can't move referenced elements, but you can copy them and get a stacked duplicate.
