Tenant dropdown bug [Alpine issue]

Trying to set up multi tenancy for the first time, and when I click the tenant dropdown I get:

Cannot read properties of undefined reading ('toggle')

Cannot read properties of undefined reading ('toggle')

Cannot read properties of undefined reading ('toggle')

Cannot read properties of undefined reading ('toggle')

Looking at the alpine code for the button I see this in the

toggle()

toggle()

toggle()

toggle() function:

toggle: function (event) {
            $refs.panel.toggle(event)
        },

toggle: function (event) {
            $refs.panel.toggle(event)
        },

toggle: function (event) {
            $refs.panel.toggle(event)
        },

toggle: function (event) {
            $refs.panel.toggle(event)
        },

I'm assuming $refs.panel is undefined. Not sure what isn't configured correctly.

Appreciate any help
