Why Are Monitors Still Existing?

The Monitors ceased to exist at the end of final crisis, why are they in the current Justice League Series?

Possibly because now we're in a different Multiverse, different story and continuity.
Every time DC reboot, the Metaverse adjusted to preserve Superman, and the story follows.
So even if the Final Crisis happened in the history of Rebirth, then it didn't happen the same way as Post Crisis. No idea how exactly that works though.

The monitor not exactly is The monitorS.
The monitors were come from the original monitor when COIE ended, And in Final Crisis, The monitors died and merged together become the monitor again

Original monitors exist in all universes why would it exist post-crisis after it ceased to exist while in Crisis.

For the same reason Doomsday and Bane keep cropping up. DC once made a bucket off them and hopes it will sustain.

Realistically: Snyder wanted to use everything. (And even then, at least Nix Uotan survived FC).

In universe: Someone has to try and keeps tas on the current mess.
