Copy and paste 2 levels of nested content causes duplicate content to show.

[Myster]

I have uncovered a bug in Umbraco. If anyone uses the copy and paste feature when there are nested children then the children don’t get a new GUID, they get a copy of the old GUID , which causes the content to come out duplicated in the front end.

In the screenshot, #1 copy has a child #2 so if #1 is used then the children items don’t get a unique GUID and so they will be the same as where they were copied from., but #2 copy can be used.

The workaround is to delete the items at level 2 and re-create them

you can copy and paste items at level 2 and it will not cause an issue, because there are no child items to mess up, so a quicker way to re-create the level 2 items is to copy and paste them, then delete the originals

I am seeing this issue on Umbraco version: 8.6.1

Hi @Myster, I believe this is already fixed in 8.7 by #8842. Can you recheck on the newest version of Umbraco?

Thanks @rbottema - good suggestion, but that is specifically for the block editor, this bug is fixed in v8.6.2, I would recommend you upgrade to the latest v8.6 at least.
