Source Movement Module Issues

Forgive me if this is a basic question, but I browsed the forum and didn’t see any direct solution. I’ve applied a “source movement” module to my vfx in cascade however the source of the emitter doesn’t move as intended. I’m trying for a ‘smoke trail as a spaceship lifts off’ kind of effect, however the only other solution I could think of was messing with ribbon emitters and trails. I feel as though this should be simple but maybe I’m missing something basic. I tried to add a few different location modules to after it didn’t work at first as I thought it might be like a velocity/time module where it needed a location to start at before it worked but that failed too. Help is appreciated!
