Which Lan-Cay contract do I have?

[Misfit-45]

Hello, I have two Lan-Cay PI black blade M9s. with the scabbard date of "98".
Here's a quote from M9bayonet.com

" The Lan-Cay second contract ended in the second week of April 1997 with all bayonets being furnished and accepted on time."

The next contract was the 1999 split contract with Ontario which was completed in June 00.

Where does the "98" date fall since it is between contracts?
