Kill KillaVolt Objective not triggering

Basically as shown, im stood in the area that a container should drop and spawn the named enemy, Trudy, but they’re not dropping thus i am quest stuck here. Any ideas? otherwise i guess i just ignore this sidequest and hope it fixes itself?

ok it triggered as i left the area, because i went for the battery first, i think i may have managed to jump around the spawn trigger as its roughly level with the side path to the battery. a PSA then i guess!
