Can't remove components from tabbed container

The tabbed container component seems a bit broken. Once you add something into it (in my case a form), if you take it out and try to delete the tabbed container, it also deletes the form :confused:

Copying and pasting seems to be the only option, but that means I have to rename all the fields in the form.

As a work around, whatโ€™s worked for me is, after moving out the components, rename the parent container, then hide it on desktop, then you can delete it.
