Inline conditions in targeters not working with the "EndProjectile" mechanic

Conditions on targeters do not work and get ignored when used on an EndProjectile Mechanic

I am currently using:

• EndProjectile @EntitiesNearOrigin{r=2;conditions=[ - isCaster true ]}

The condition isCaster is being ignored and the targeter will default to @EntitiesNearOrigin, I have tried using other conditions to make sure it's not an issue with isCaster & I have used the example format on the wiki
