Unable to delete slice (Designer, Export persona)

[Paul Masri-Stone]

There's an unexpected extra slice appearing in my list of slices. It's not one I intentionally created. What is it? And how can I delete it?

 In this image, it's the top one, labeled Player. It has a different icon from the other slices. I cannot select it in the document, only in this list of slices. The trash icon is greyed out when it's selected. Backspace doesn't work.

Uncheck the checkbox.

I tried that. It doesn't get exported. But it's still there (which annoys me 😆 ). What is it? Is it for the whole document and is that always there?

(And I'm wondering why it's labelled Player when I've saved the document with a different name. Although it may have been a Save As from a document that was originally called Player.)

is the layer or artboard named Player?

There is no artboard. There are a number of layers named Player but there are also lots of layers not named Player. The document is saved as Controls, but as I say may have originally been Player (before I started using the Export Persona).

That is because (as you now know) it represents the entire document, not any single slice of it, so it has the standard 'dog-eared' page icon of a generic document.
