Used OCLP to upgrade

Hi, I just used OCLP to upgrade my iMac14,1 to Sequoia, very cool and worked first time. I also use bootcamp to dual boot Windows, by holding option at boot. After the install I unticked Show Open Core Boot Picker and rebuilt, because I wanted the mac to auto boot. This worked, but now when I hold option and select Windows, mac boots instead. The windows install partition is still there on the hard drive.

How can I fix this - so I want the mac to auto boot into mac os without pressing any keys, or be able to hold option and choose windows from the menu, to boot into windows. Thanks
