You're not crazy (at least not about this).
There are four movies:
"Universal Soldier" (1992), with Van Damme;
"Universal Soldier II: Brothers in Arms" and "Universal Soldier III: Unfinished Business" (both 1998), both without Van Damme;
and "Universal Soldier: The Return" (1999), with Van Damme.

The two in the middle were made for TV by a Canadian company.


Später.
