Does the Layer Tree get corrupt?

Hi - I ran in to a Layer Tree problem once again.

I have a Contact Form that doesn’t show up in the Layer Tree in my project (it did earlier in the development), so I exported the Bloc with the Contact Form as a Custom Bloc, and then opened a new project and placed that custom Bloc with the Contact Form on the page, and all the CSS is correct, but the Contact Form still doesn’t show up in the Layer Tree.

I can select the elements of the Contact Form, and the right Inspector does show correctly, though.

Thoughts?
