trouble understanding general rules

[Tupsi]

I have a network setup with an "allow all out" rule which you can see in the screenshot in the first line. Still I get that second line claiming hitting the "default deny rule". That is the part I do not understand. Why is iptables ever getting to that point when I have an "allow all" in my rules?

Obviously this are out of state packets:
