particles are not spawning

Im making a block that is like a dispenser, but it dispenses a specific particle.
on the redstone trigger, I check if it has the necessary items, it checks the blocks rotation, adds an offset based on the rotation, and then it should spawn the particles.
However, the items are being consumed, and I know that the particle location code is right, but the particles still don't show up.

one of the particle blocks specifies that it is server side, and the other one does not, I think that may be one of the issues.
However, the one that says server-side does not let me specify velocity or direction.

These are the relevant parts of the procedure
