Hmm, I wonder where that came from? I searched back from snapshot through 23.05 and can't find a -v1 variant anywhere...
Try this to fix it, log in via ssh:
echo 'luxul,abr-4500' >| /tmp/sysinfo/board_name
ubus call system board
The output from that ubus call should now show board_name being just luxul,abr-4500 as above, without the -v1 suffix. Once that's all done, try redoing the sysupgrade and it should select the proper profile.
(Note that overwriting the /tmp/ file is transient, so if you reboot before you do the sysupgrade, it will revert to the -v1 version and you'll have to do it again.)
