Enemies Only Targeting Filter Targets Allied NPCs

Platform: Playstation 4

I've been experiencing an issue with the targeting filters on Playsation 4. I'll use the button combination R1 and Circle to set my targeting filter to target Enemies only. The filter name in the HUD says enemies, the configuration settings have only enemies selected as options, and yet the filter still targets green named NPCs. I searched through existing bugs and saw this reported several times in 2013 but nothing more recently. The filters and ability to quick swap between them seem like they would be an awesome feature, but the enemies only filter appears to be fundamentally broken.
