Question Output Particle URP Lit Quad particles are invisible

As the title suggests, I can't get the URP lit quads to be visible in my scene/game. They are there, because if I click the game object containing the VFX graph, I can see the outlines of the generator but not the particles themselves. At the same time, the non lit basic output particle quad works. Same story with all Lit Quads and their counterparts.

I am running Unity 2021.2.9f1 with URP 12.1.4 and VFX graph 12.1.4 which, according to my searches and the documentation, should be able to run lit URP quads. I'm attaching a couple of images with the stated issues.
