Repeated message saying Windows Defender and Comodo Defense + are both off

Since I installed Windows 10, I get repeated messages that both Windows Defender and Comodo Defense + have been turned off. When the popup takes me to the Windows Security and Message screen, I can’t turn either of them on. However, my Comodo status screen seems to indicate that everything is okay: Antivirus/Stateful, Auto-Sandbox/Enabled, HIPS/Safe Mode, Viruscope/Enabled. So is Defense + actually working and the warning message is just a glitch?

The warning by the security center is a glitch.
