The drop down list for pick previous firmware doesn’t have ArduPlane 3.9.(3-10) available. I also cannot upload a firmware by selecting a custom firmware.

It seems Michael is behind the schedule of refreshing the historic fw database.
Till he have time to catch up, you can always download previous versions from http://firmware.ardupilot.org/Plane/ and upload as custom firmware.
