Calling org-babel-lob-ingest on a file with code blocks seems to work
only for the current Emacs session, and doesn't seem to affect the
variable org-babel-lob-files.  If I quit and restart Emacs, it's as if
I never loaded a file with org-babel-lob-ingest.  Also I see
"(mismatch)" next to the "State" button for org-babel-lob-files in
Customize.

Like this...
   State: STANDARD. (mismatch)

Have I found a bug, or am I doing something wrong?
