[O] Trouble with logbook drawers

[Michael Welle]

Hello,

I have a few repeating tasks with defective logbook drawers:

   :LOGBOOK:
   ....
   :LOGBOOK:
   ....
   :END:
   ...
   :END:

As you can see, two drawers got nested somehow. They both hold data that
belongs to the task. I can't say if data is missing, but there seems to
be no duplication of data.

>From time to time I fix them manually, but they tend to come back after
some time. Any hints?
