unwanted unknown layer in the layout

Some block show this unknown layer when instantiated.

This layer is not there in the layout.

The outer rectangle should not be there.

any suggestion is appreciated.

apologize if this turns out to be a very basic question.

Did you try the Dynamic Selection assistant to see what's in the region where this rectangle is?

There is an issue where bounding boxes are wrong - but that doesn't seem to be what you're describing: Reason for cell's large-sized boundary or bounding box aka bBox area or extent of layout. SKILL to delete steiners, markers, guides, remove invisible ghost layers, shapes.

I tried with the Dynamic Selection Assistant, it does not show anything when I hover my pointer on this box both in the original layout and when I instantiate it.

I unchecked 'Valid' in the layers panel setup but I still do not see the box.

I will check your link.

I'm guessing the white line in your picture above might just be because you've selected the instance? If so, it could be objects in the underlying cellView. That is usually obvious if you open the underlying cellView and try fitting to the cellView and you end up with a lot of space around the layout - the article I mentioned should help in that case (probably) if it's not a real (but invisible) layer.

Yes, I need to select it se I can see it.

Yes. When I open the layout and press 'f', I see large empty area around the layout.

I will check the link.

I tried the solution related with the steiner in your link.
Thank you!
