Did my Radiesse injections leak out of my cheeks because of the cannula method? What happened? Can it happen again?

I had radiesse injections in my Cheeks in several locations. One location was injected with the canula method at the outer lower cheekbone (injection site )to up under the skin towards the inner tear trough. On my way home. I noticed a whitish/pale pink baking powder like subtstance leaking out of the injection site,wiped it off, more leaked again. Was this RAdiesse ? what went wrong? It did this 3-4 times , with tiny amounts (size of plastic pin head) and then put a bandaid on. Common problem?
