OpenWRT rebase on final 21.02 release?

I’m having trouble with installing kmod packages that I have built. I’m am building kmod-ipt-netflow
Opkg is reporting an issue with:
pkg_hash_check_unresolved: cannot find dependency kernel (= 5.10.82-1-a4043683d4709f4e4d5c9b450aefabb2)
and Checking kernel version
kernel - 5.10.82-1-b5bef3d4b31dc59739cc3fec5a69297b

Does this mean there is a discrepancy with the sdk kit and the image running?
