Random Unit didn't work?

[Zucth]

Anyone know how to do this? I did it and all neutral are work well, but as a units it didn't start to cycle at all...
What did I missed here? Or is it doesn't work from the start?

In case you're trying to test and of these random things using the Test Map feature inside the editor, make sure you're not running on fixed seed.

File → Preferences... → Test Map → Untick Use Fixed Random Seed

I did play on both test and warcraft to check but it didn't work on both of them...
