Different office, different rules. I've done mine (and I know of others too) who have had on-line reports approved after being out of the country, and I also know of folk who've had them approved after obtaining a new passport where others have said this is not possible.
No real way to define the rules and just have to do what your office requires seems to be the solution.
Edit. The good results I mention have all been from Jomtien immigration.
