Sybase DB auto extend - multiple devices

Hi

I have a database that 3 data files, only one was created during the installation of SAP and the DB, the additional 2 (data_002 and data_003) were added later. I have automatic DB extension running on the data_001 device and it was setup during installation and it is working. On the additional 2 devices auto extend is active but it is not working. I activated them in dbacockpit. Below is the output of exec sp_dbextend 'list'

type name segment item value status
