In my typical OO file I have two columns, a text column and a checkbox column to the right (so I can keep track of things in my notes requiring follow up).

I haven't yet tested to see whether this problem relates to OO4 or OP, but it only happens on OO4 when files are synced with OP so I think that may be the source of the issue. Once a document has been synced, the ToDo checkboxes move to the left of the text inline with the text (as opposed to in a separate column). Not sure if you've seen this behavior before.
