Ignore the expiration timer.
Considering that periodically ExDefUT 1 and 2 are being changed, this trigger should spawn only 1 unit and change it every 2s. Sadly, it keeps spawning units every 2 seconds. How do I fix this?

What exactly are you trying to achieve here? It's a bit confusing to me.

If you always Remove ExtDefUInfo 1 and 2 then check if they're equal to No Unit afterwards isn't that check redundant? You know they have just been Removed from the game. Also, how are you going to Replace a Removed unit? It's been removed. As far as I know you can't interact with a Removed unit at all just like how you couldn't reference a Point that's been destroyed.

This is your code:

remove unit_A
remove unit_B

if (unit_A is null)
  create unit
else
  replace unit

if (unit_B is null)
  create unit
else
  replace unit

In other words, due to you removing units, both conditions will always evaluate to true
