After upgrade all new segments pre-processed

Hello,
since we upgraded to version 4.3.1 last July, all new segments are pre-processed. We have
no entry “enable_create_realtime_segments = 0” in config.ini.php.
According to the description the default should be processed in real time. But it is not.
An entry “enable_create_realtime_segments = 1” unfortunately changes nothing.

Our current version is 4.9.0
