AS923_2_DR6 failed when ADR off

Hi,

I have CubeCell-AB02, I want to know how to enable theAS923_2 DR6, I changed the config file to this

when I enable ADR, the server can receive DR6 sometimes, but when I turn off ADR, node will keep send DR5 instead of DR6. I want to know how to fix the channel to DR_6 shen turn off ADR? I changed the config file like this, but not work.

The arduino version of cubecell library I used is v1.3.0
