Guild Wars 2

I am trying to have the trait “deployable turrets” on my charr engineer, however, I cannot select that option when I try to. Instead, I see it replaced by “energised armor”. Has deployable turrets been removed? I am a level 59 charr, with 20 invention, so I should be able to select that as an option, but it won’t let me.
Option V should be deployable turrets but is showing energised armor. Any ideas as to why this is?

Deployable Turrets is TOOLS: V

That’s weird, on the gw2db website, it’s under inventions. Thanks so much for clearing it out for me
