thanks for your response and hopefully it
becomes clear how this happens.
I did follow all the guides (the site wouldn’t work otherwise,
as I noticed before I had set up everything correctly).
It still persists btw.
Almost everything like the skills to the footer
sections are reverted back to either an earlier version
of what I had or the theme’s defaults (the latter
I think only because I hadn’t changed those sections yet).
Even after refreshing and exiting the live editor,
it doesn’t show the same data I put in as the
detailed Integral options (and things only correctly
update when I change them there, not when I do it
in the customization live editor from the Appearance menu).
