I think I have the same problem. Also some "TODO" keywords are now
highlighted in some headings but it could be related.

In the "*messages*" buffer I have:
font-lock-fontify-keywords-region: Wrong type argument: listp,
org-level-1Error during redisplay: (jit-lock-function 240) signaled
(wrong-type-argument listp org-level-1)
