Complete Bloc Disappears After Editing

I have a three bloc page I’m working on and I edited an element in the third bloc the entire bloc had disappeared from the layers list.

I can still edit items but the entire bloc does not appear in the layers list.

Norm,

Can I ask you to a take a look at this?

I had to recover the page from a previous backup and it has happened again.

I added a modal to a DIV and the modal created was one character wide.
When I deleted the modal the BLOC that contains the content disappears from the Layers tree making it impossible for me to manage and edit content from the Layer tree.

Would you be able to share a copy of the project file please?

Is there a way I can send you this file privately?
