Opencore - Booting into Windows resets default boot option

[ainsleyclark]

Hi there,

As the title suggests, when I boot into BOOTCAMP - Windows from Opencore, it boots absolutely fine, I then restart and and it boots into Windows instead of using macOS.
I have set the default boot option by using Control & Enter at the boot picker. Setting a default startup disk doesn't seem to work, I select macOS, restart and it boots into Windows.
Is Windows resetting NVRAM? Is there a way to prevent this?

Interestingly when I boot into Windows from Opencore it adds itself into the top boot priority even though I have everything else disabled apart from macOS.

Any help would be appreciated.

Many thanks.
