Hi
The only way i have been able to get zones away from edge-cuts is by increasing line-with of edge-cuts.
This is ofcourse not good.
adjusting the clearance of the zone will adjust all clearences not only to edge-cut
this setting should acutally be under: design-rules, edge keep-keep-out
or ?
is there a good way to do this ?
Welcome to the club - been there about 12 20 months ago - been told it’s OK as it is.
Sorry.
hehe
well its not OK as it is.
Lets fight 
fight for a change that is…
I don’t have time to program on yet another project, so yeah, feel free. The bugtracker links should give you something to work with I guess as someone even posted a first band-aid solution - no idea how that one holds up for the remainder of the code though 
It looks like a bug to me. All I can do right now is to tell I’m affected by this bug and suscribe to the bug report to increase its visibility.
