Enemies object spawn after beating them in Nameless Pass

I found them after making a round about as it can be seen in the map. I’ve been clearing them, and they spawned as an object that didn’t attack.

I think there was a same case before the first patch update but it’s my first time seeing this in the nameless pass. I’ve attached the video and the rest info about the dxdiag etc in the link below. Thanks!
