Upgrade to krypton on libreelec

So last week we decided to make the move from jarvis to krypton. As always I needed to change a few settings on my nuc. I have always had to change the video output to HDMI, then I select blank all other displays. However, now on krypton, it turns the main screen blank. It is still on and a reboot is necessary to regain anything on the monitor. I have the version on my phone as well as our laptop, both are fine, heck they are a great improvement! Just need some direction, os is libreelec btw. Thanks in advance.
