how to modify the type order?

Hi:

Thank you so much for the plugin. It looks great.

My question is how to change the order of types, see the screen shot.

Above the gallery, it shows different types which I give in each portfolio.
The default order was arranged alphabetically,
I want to re-arrange the order, such as put “others” at the end. Could you please tell me how to fix it?
Thank you in advance.
