Self-signed CA issue

Im using RouterOS 6.2 at RB1100AHx2.
As of new features of 6.x i am trying to manage certificates with self-signed CA. But i cant complete the first stage:
/certificate ca create-self-signed-ca common-name=“common-name” country=“Russia”
crl=1.2.3.4 days-valid=365 email=“test@gmail.com” key-size=4096 locality=“Tralala” name=“testCA”
organization=“Squirrel Inc.” state=“Thestate” unit=“Reception” ca-passphrase="super_secure_pass"Router always returns: failure: failed to generate certificate
I have tried a lot of variants of values, with and w/o quotes, with various ipaddresses and other string extensions. No effect. Anytime.
Have anybody been successful at that operation?
