I got that feedback from SRAM Support asking them the same question:
"Because firmware version 2.17 was out to the public for some time and then removed from our servers, the AXS web references both the currently available firmware and your current firmware, see the difference, marks this as a flag.
Having firmware 2.17 is perfectly fine and you do not need to update the firmware, but because the AXS web sees a mismatch, it is sending alerts.
For now, please ignore the update messages from the AXS web. We are hoping to have another firmware update in the near future to correct the issues you are seeing, but unfortunately do not have a set date."
