Loop tools not working on 2.8

Hey

I am using 2.8 trying to add loop tool circle. 

Im pressing circle, but absolutely nothing is happening, could this be a problem with 2.8 or is there something im missing?

I've tried doing it with more vertices, tried playing around with the flatten, regular and radius. Ive even tried doing it on a different object but getting nothing.

Any fixes you know of?

Cheers
