Node group associations

Hi,

Under Node Group Association, when I try to add my Aeotec Z-Wave Stick to Lifeline group, there is not button to click “Add to group”. Is this a bug?

When searching for this problem, i see multiple screenshots with buttons for “add to group” and “remove from group”, but these buttons don’t show.

I’ve run into the same issue trying to debug why a device isn’t sending any notifications. I’m guessing this is an interface bug, the buttons seem to be there, just hidden.

In my case, I’m even missing the ‘Node group associations’ label also, the buttons are there, but not visible. When you hover your mouse over them, a blue square appears, but the text of the buttons isn’t shown:
