This setting is on purpose, it reflects the mode the servers listen in when not 
You can change the default mode in the Mode menu
E.g. on 10147 kHz the servers use PSK500R, on 10148 PSK250 is used as default.

Best profile on 10147 is 9 or 8, on 10148 (intermar servers) it is 5 (PSk250).

Pskmail automatically sets AFC on. You can limit the AFC range in the fldigi 
config->modems menu.
I normally set the limits to 10 Hz.

You can set the mode for APRS and connect requests. This will also be 
the default for the client. The client resets the mode to default once per 
when you are not connected.

The TxID, RxID and mode are controlled by the server in connected mode.
It is best to leave them OFF during non-connected times, 
to prevent other stations from changing your listening mode.

server default mode is experimental. and is not used yet.
The servers can set a pair of default modes, this is not done yet..
