Weak Auras import problem

Hi!
I've been using weak Auras since 5.2 started and so far I love it, at first i did all my weak Auras, but then i learned how to use import.. only problem:
I can't import from the chat window, you know, when someone shift-clicks a WA, i can't import that, i can import from strings, but it's rather inconvenient to have to have someone link all that text in mumble..

What could cause this?

ElvUI? prat? (i don't use prat since i use ElvUI)

Did enyone else have this problem? any idea on how to fix it?

Thanks!
