Blueprint not working

[MaluNoPeleke]

I get an error "TypeError: Cannot read property 'current' of undefined" in the blueprint for individual Matomo page statistics while using Kirby 3.6 alpha:

matomo:
        type: matomo-page
        overview: true

TypeError: Cannot read property 'current' of undefined
at a.currentLanguage (index.js?1629713017:formatted:12463)

at vn.get (vendor.js:6)
at new vn (vendor.js:6)
at a.t.$watch (vendor.js:6)
at _n (vendor.js:6)

This is the mentioned line in the code:

        currentLanguage: function() {
            var e = this.$store.state.languages.current;
            return !!e && e.code
        },
