Navigation with the arrow keys

In previous version of D5, I was able to use my keyboards arrowkeys as navigations tools. For some reason, in latest releases, It’s not working anymore. The arrow keys up and down are locked by a function I’m never using (“navigation up in the list”), greyed out, and impossible to change (see attached pictures). Is there a way to allow the user to reset this ?
