Xdj rx waveforms take so long to load

So I plug in a usb stick, load a track into deck one/two but the waveforms take sooooo long to load and a couple of tracks only load to a certain point.
Is there an upgrade of any kind for this to make it faster?
It's been a while since the last time being on a set of pioneer cdjs but I'm sure the wave forms used to load up within seconds.
I mix tracks fast and use the wave forms to see where I am on the track so it's quite annoying.
Thanks
