I am having several errors with frontity-chakra-ui-theme .. with mars they weren't

hi there
it’s my first post, and my first frontity test :slight_smile:

I installed frontity and connected it to the online version, with the mars theme I have no problems: I can visit home, archives, posts, and pages.
after that I installed frontity-chakra-ui-theme and unfortunately now only the archive pages are visible.

there are several errors in the console
you can see the site at https://headless-ochre.vercel.app/

and also page 404 https://headless-ochre.vercel.app/blabla/

however if you try to click on the menu no page is displayed and the site crashes

headless.module.6a8ea72fc90f67c8c406.js:19 TypeError: Cannot read properties of undefined (reading ‘96’)

archive.module.40d6941f1b925a623150.js:1 Uncaught (in promise) TypeError: Cannot destructure property ‘title’ of ‘t’ as it is undefined.
