Hi caroline.dunne,
Is it possible you have an archived list with this name? It wouldn't be possible to create another, and that may be where it is hiding.

If not, you may also want to look in your Favorites to see if you have a list that was pushed up there.

Last, keep in mind that lists and Smart Lists share a namespace so it's only possible to have one or the other with a name, in case you have a Smart List with the name "Garden" already.

Hope this helps!

Thank you, I've managed to find it.

It was a Smart List saved as a Favourite but hidden as it had no items in it. I had already deleted the list Garden* which it was based on.

Very odd!

Hi caroline.dunne,
Ah yes, hidden because it was empty, that makes sense! You may want to review that setting as well if you want "empty" Smart Lists to appear in the left navigation bar.
