Dropdownlist jumps to the top after scrolling down and selecting an item

Hello,

Dropdownlist doesn't let you choose item after the first six items. When I scroll down and select an item, it automatically jumps to the start of the list. 

Best regards,

All dropdowns contains > 6 items. Works perfectly. What's wrong?
