/etc/novell-release showing wrong version


I have a server running OES 2018 but when I run


cat /etc/novell-release


the output is incorrect. This is what I see for the results


Novell Open Enterprise Server 11 (x86_64) VERSION = 11 PATCHLEVEL = 0


It's worth noting that this server was upgraded from OES 11 SP2 awhile back. Anyone have any suggestions on how to properly fix this? Thanks!
