Good app.. Whats up with Export??

I love this app but one minor issue when exporting.. I might not have ears of quality but why is there like a faint tick or sound before playing a loop inside the track. I gone through hell to update this app how it takes forever to download. I assume it fixed it problem but nope.. It even done it on raw playback. Not even quality differs this effect. Well.. I might as well go back to my PC with FL Studio 7... Smh......
