Button or link dissappears after adding login link

I’ve created a page accessible to members only. And now I’ve added the link to open up the login modal (#/ms/login). But after I’ve done that the Sign-in button I’ve created disappears on the published site. You can see it briefly while the site is loading but then it disappears. The same goes for the ‘Sign In’ link in the footer.

Can anyone explain what I am doing wrong?

See this Webflow staging site: https://ishagold.webflow.io/. There should be a Sign In button in the top right corner.

Thanks!

The problem magically solved itself. Must be a Webflow bug!
