How to delete Page setup names from list ?

In the upper left corner of the Plot Display is the Page Setup list. In it there is every Layer State that I saved. How do I shorten the list ?  There is an ADD button, but no Delete. Any Help is needed.

I'm not sure about the layer state being saved. However, if you want to delete or shorten the list shown in upper left of plot display.

Type pagesetup while in paperspace unless you have them in model as well.  Your list of saved page setups will be shown.

Select an unused pagesetup and press delete key.
