Changes don't apply immediately (until clicking something else)

I’m running Mac Sierra, with NLP v2.2.0 and LR Classic. I had a similar issue before, but with v2.2 I have the same issue. When I click convert it doesn’t actually apply to the image until another operation is performed (clicking a slider etc).

I get the same problem when selecting a new “Tone” profile and other select inputs, they doesn’t adjust the working image until I perform another operation. The Navigator preview does update though, which is odd. It’s not a big problem really just a bit jarring.

Looking forward to playing with v2.2! Looks great already.
