Visual Studio 2017: Ruleset won't execute - visual-studio-2017

Question

I want to define a custom set of rules to be checked at compile time. But it seems not to work.
Example:
I choose one rule directly and I'll get the expected warning.
But when I instead create a custom ruleset containing the exact same rule then I won't get the expected warning.
What could be wrong?
Edit:
void f(std::string& i) {
std::string s = i;
cout << s;
}
int main()
{
std::string s ("abc");
f(s);
}
This gives me the expected warning Warnung C26460 The reference argument 'i' for function 'f' can be marked as const (con.3). in the first case.
Even if I create a custom ruleset including all available rules, I won't get any warnings.
Here you see me selecting the custom ruleset:
Edit: The ruleset action must change one time to enable it.
When I create a new ruleset containing only the const-checks then I will get a .ruleset that does not work and look like this:
In the ruleset editor it looks like this:
When I then change its action from Warning to Error:
Then the .ruleset gets additional lines for each test case:
When I change the action back to warning it looks like this:
Now it is working as expected.

I've been able to reproduce your error with Visual Studio 2017. I don't know exactly what I changed (or if I changed anything at all), but I am able to see the code analysis warning you expect with a custom rule set.
Things I would try:
Double check the Error List window is visible and not hiding somewhere.
Open the rule set file, change the Action to Error and then back to Warning and save it. I wouldn't expect this to be the problem but it's one of the things I did and after which I started seeing the Error List window.
