Not able to import themes

Hi Guys - I have downloaded a few different themes onto my macbook, but when I import style in the style preference everything is grayed out.

I am trying to import the Asian Efficiency theme, but have tried others to check if it was the theme or not.

Is there something I am missing?

Might you be trying to use an OmniFocus 1 theme? It’s possible that 2.x may import old themes but the formats are entirely different.
