How to change store_forward period

I used FX30 with FW3.3.0 now.
To check FX30 performance, I checked “store & forward” function.
To change period for “store & forward”, I modified "/cloudinterface/store_forward/period value in “Resources” to 90 from 60.
But FX30 is sending message at 60 sec. Why I cannot change period for “store & forward”?

And FX30 cannot send message at every 60 sec.
FX30 tried to send message at every 60 sec but almost not send message. Please let us know why FX30 cannot send data at every 60 sec, please see attached picture file.

Hello Takashi,

Please test Store and Forward with Developer Mode set to Off.
