Windows Vista does not recognize Comodo firewall after latest update (3.13.120)

Hi

I have been using Comodo firewall for quite a few years now. And it has been working fine.
As the windows Vista recognized Comodo as the primary firewall and kept the window firewall off.

After the the last 2 automatic updates of the Comodo Firewall (3.13.120417.573) it has turned on Windows Firewall on Vista ! Now Windows firewall is running together with Comodo.

I noticed it first time after the 2nd last firewall update, I was expecting it might be resolved with the next Comodo Firewall update. Then there was another update but the issue still remains.

Isn’t this a bug?

Could I manually fix this?
