RTL problem

Hi @ach1992!

Please open up this file:
\wp-content\plugins\smart-slider-3\library\media\admin\dist\smartslider-backend.min.css

and write this code in the very end of it:

html[dir="rtl"] #n2-ss-slide-canvas-settings .n2-ss-settings-panel{
    right:0;	
}

This should solve the problem you see, just press Ctrl + F5 (hard refresh) in your admin area to make sure not a cached version of the CSS file will load, but the new version of it.

This fix will be included in the next versions. If you would see anything else wrong, please let me know!
