Design Options - added components are deleted

[adamskaEXHPY]

Hi there,

I have a serious problem when creating the design options (never happened before) - once I select and add elements to an option, they are deleted - not copied to the sets.

Any idea how to solve it and what causes that?

Thank you!

Your working View is in another Option and/or the target Option is not Visible.

Hi,

unfortunately not the case - it was one of the first things I made sure are fine.

The view settings have the <primary> design option applied + I am in the Main Model view so it should be fine. Also, I am quite sure they are deleted because I get a bunch of warnings of unenclosed rooms.

That message only indicates that the room isn't bound properly.  Also, indicates to me that you are moving a bounding element, such as a wall, to another Design Option - one that is NOT visible in the current working View.  I doubt seriously it's being deleted from the Project.  The explanation lies elsewhere.
