[Bug Report] Gnome-a-Palooza not spawning gnomes consistently

Platform, device version and operating system: Playstation 5 GoW ver 9.3.0r83640

Screenshot or image: N/A

What you were expecting to happen, and what actually happened:
Triggered Gnome-a-Palooza, a few minutes in normal enemies started spawning, killed 2-3 sets, exited back out to main screen to check timer - 9 min left. Went back in (Farming Summer Isle PVP Blood Frenzy) - gnomes spawning again. Got 2-3 sets then normal enemies came back. 3 sets of normal PVP enemies later, gnomes returned for another 3 matches. This kept repeating for the entire duration of the GAP timer. Expected behaviour: only gnomes spawn.

How often does this happen? When did it begin happening?
This was my first Gnome-a-Palooza of this weekend. It did not happen during the previous Vault event. Triggered one more - same behavior.

Steps to make it happen again
Trigger another Gnome-a-Palooza, second attempt better data was captured:

First 5 minutes - all Gnomes.

Then the following battles were fought (Same area as listed above):

1 - PVP Enemies
2 - Gnomes
