Inteligent Playlists super slow

Hi. Can you please let me know why this is happening.

I created a number of inteligent playlists with criteria like this:

- any of the following conditions:

author = avicii

file name contains = avicii

Problem : when I scroll through the playlists and when I hit the inteligent playlist I cant press any button on Rekordbox - looks like the playlist is refreshing every time I click on it. This will take around 20 seconds when I completely cant use the software. Music will still play fine but as we can imagine 20 seconds can break whole set. 

Im using a Asus laptop model 2018 with 8gb ram, ssd drive internal, intel core i7 8550U windows 10 pro 64 bits. All music is stored on the USB 3.0 external MSATA HDD (much faster than magnetic 3.0 usb HDD's).

Is the condition for file name contains a killer for a playlist functionality? I have a option to load playlists faster in Rekordbox ticked, PC is running on Performance mode as well. Hope you could sugest something?

PS im using ddj 1000 with latest firmware and Rekordbox is latest version also.

Thank you
