Search function not working properly

Recently upgraded my MacBook pro to Sierra OS and since then I am having trouble searching for songs? At three recent gigs when searching - the song that was playing just stopped and replayed from the start and another time a sound like a gun shot came through!! I kid you not!!
DJ pro is not boosting my confidence at the moment? Is this a sierra issue? Thanks Lloyd

Thanks Lukas - I have disabled the keyboard shortcuts now - all seems ok but i still have to click search twice to search - is that normal?
Thanks again

Hi Lloyd Bracken,

thank you for your post, this is not a Sierra issue. Could you check if it is possible that while typing you are going out of the search bar? That would explain the sampler sound (=gun shot) being triggered by a keyboard shortcut.
