Cannot edit the starting page using elementor

Hi,

i need help with the better health theme. I cannot use elementor to edit the first page of the demo data.

The message is, that i need to add the “the content” Function in the template, because there was not found a content area”

When i add this function in trhe template, i see all content of the page, but i cannot edit it.

Is this a known issue?

Thanks for helping,
Bastian
