Template Switcher Issue - Protean

I have been doing some testing on a couple of sites and happened to notice that 1 of the sites were no longer updating any changes I was making to the CSS Styles.. I use Protean with a custom CSS Style Mix by default for my websites and Chrome as my browser. Here is what happens... 

If you go to the bottom of the page and click Design - You will see all the templates you have installed like below (I have Protean and Lucid):

If you click ANY of these, you cannot get back to your own Custom CSS you may have for Protean. So of course, any design updates I was making to my Custom CSS Style Mix was not reflecting in Chrome. I cleared the files and images cache in Chrome and it still didn't work. I had to clear the Cookie and Other Site Data (which signs me out of every website I am logged in to - pain in the ass). THEN I was able to see the my custom CSS Style Mix for Protean. 

You need to add a regular Protean into the choices that will allow you to go back to Protean using whichever Style Mix you have set for your site. Maybe even have (Default) next to whichever is set to default in Studio > Designer.
