Village raids

When I was Defending the village from Pillagers, it said there were 2 more raiders, but i kept looking around and I couldn't find them

What I expected to happen was...:
to find the Pillagers and kill them

What actually happened was...:
I could not find them, no matter how hard I looked

Steps to Reproduce:
I think it happened because I killed them when the health bar at the top of the screen was not there
