Great App, but theres an error, plz read

I bought, "sliders have a chance or randomly give u a gem," but it doesnt work, I also have a chance for sliders to clear screen which clears the screen a lot for a chance, but a gem is also a chance, but it NEVER happens, plz fix in an update soon, other than that, GREAT APP!!!
