Make R# 2016.1 cleanup to enforce curly braces in single-line "if"

R# 2016.1 stopped to add curly braces when cleaning code

Before it worked, if I had code like 

if (IsEmpty)
    return null;

R# cleaned it to 

if (IsEmpty)
{
    return null;
}

But after I've updated to 2016.1 it doesn't work anymore. I had specified all possible settings in Code Editing \ C# \ Code Style \ Braces and set everything to "REQUIRED" but it seems it doesn't give any effect.
