Engine Prime problems

Hi i have a few problems with Engine Prime and the Mcx8000.

I created crates (automatically made when i dropped my folders of music in my collection), i have synced the database to my usb stick by pressing export to mcx8000. When i want to open some crates on the mcx it wont open and get back to the first crate at the top… Some crates are opening and i can play songs… But mostly it wont open. What am i doing wrong? Also the BPM filter acts strange, i have set it first on a range of 3 or 5 or 10 but that gives me something like this:

80-90 85-95 90-100 95-105 100-110 105-115 110-120 115-125

Why is it not like this:

80-90 90-100 100-110 110-120 etc…
