AT+CEDRXS values

Initial value set in my module is

AT+CEDRXS?
+CEDRXS: 4,“1101”
+CEDRXS: 5,“1101”

This causes large latencies for incoming data from the cloud.

When I send AT+CEDRXS=0, I do see that it immediately takes effect. My application no longer has trouble receiving data from the cloud immediately. But when I read it back from WP7702 it still shows
AT+CEDRXS?
+CEDRXS: 4,“1101”
+CEDRXS: 5,“1101”

Now after I reboot the FX30s, it shows up as

AT+CEDRXS?
+CEDRXS: 4,“0001”

Question is can someone verify what the allowable values are ?

And does this require a module reboot to store in Non volatile memory

does it work after AT+CFUN=0 and AT+CFUN=1
