müssen / gemusst ?

I found the following sentence in a German grammar book:

Sie haben alles alleine organisieren müssen.

Shouldn't it be "gemusst"?

Here is another example from the same book:

Bist du sicher, dass die neue Regelung hat eingeführt werden müssen?

What am I missing?

Danke!

This is the so-called Ersatzinfinitiv: https://de.wikipedia.org/wiki/Ersatzinfinitiv

In some cases, a modal verb or certain other verbs will appear in their infinitive form after another infinitive, rather than in the expected past participle.
