+Projectile not visually working correctly with 2 weapon sets

Playing on my Tactician, crafted a +6 level of projectile skills, got lucky and the mod was fractured. However, I have a second set for ballista, with a +4 level of projectile skills and this +4 is applying both to my weapon set 1 and 2.

Stranger still, when I take both weapons out and only have weapon set 1, the +Projectile does not work. It is only when I put a second weapon set, does the +Projectile work, but all skills are only using the second weapon sets +Projectile even if a certain skill is only set up to use one weapon set.

Taking both weapons out, which ever weapon you set in WS1 is the visual +Projectile that will only show for all skills

The damage numbers definitely change when a skill meant for WS1 is told to use WS2 though, so idk if it's just a visual bug, but the damage and mana cost are now unreliable on the skills page
