I ran the wizard, it found my pump and flowmeter automatically and I selected the correct res. Left the default setting be.
This is what the page looks like now - does it need some more time? I am not able to select SHIELD in the mode area.
It does indeed generate and holds a vacuum so I am doubting that release is in fact the active mode.
One more round of doing the wizard resolved the issue - did the exact same thing, but now the configuration stuck.
Not sure what happened, but all good now.
