I'm experiencing the problem in the Indicium Mobile App (and also in the Simulator) where my default is not updating the GUI when I'm using a tsf_send_message in the SQL.

When this occurs, then message shows up as expected:

However, the numbers which are updated before (the Aantal palletten and Aantal stuks), are not updated anymore:

Am I doing something wrong?
