Adjustment Layer problem (Premier Pro CC)

Whenever I add an adjustment layer on the top of a video and apply any effect to it, I don't see any created effect from the adjustment layer. The only way to fix this is to restart PP and the effect will be visible. But this is just annoying.

Thanks any advance.

Specs:

Windows 7 on latest updates

Premier Pro CC on latest updates (v7.2.2)

I use GTX 780 (unclocked) but my CPU (i7 2600k) is overclocked (4.6ghz)

16gb RAM (overclocked)

All of my other PC stuff are installed on latest drivers too
