I'm trying to get the Versatile trophy which requires you to kill using every weapon in the game. I have the sticky grenade and explosive bullets. I tried using them all throughout one playthrough and have used them all within the same mission but this trophy won't unlock for me. I don't have any magic besides blink and I have high chaos. Is there something specific I have to do? My full list of offensive weapons are:

Blade
Crossbow
Incendiary arrows
Pistol
Explosive bullets
Grenade
Sticky grenade
Springrazor

I've used every single one of these more than once and this trophy refuses to pop up. Is anyone else having this problem?

After multiple attempts I finally got this trophy. I don't know if I was doing something wrong or if something else is to blame. Would still be nice to know if this has to be done in one mission or not. Anyway, consider this closed.
