Point light 2D odd beam of light towards camera

The problem is that the blue and red light cast what is seems a second beam towards the camera. The player is the blue 3d sphere, and the enemy is in red. The blue sphere also has a small extra circle on the left-bottom corner.

The light sources I've used are as follow: - Sun (Directional Light); - player_light (Point light); - enemy_light (Point light).

The sun also shows like the point light following a circle after the player, although you can't see it in this screenshot. Anyone any idea what I might be doing wrong? I just want the glow effect around the player and the enemy.
