Of course it's going to be deleted; you said the Colon event is 91 (hence the deletion by DNP0091).
Try setting the Colon event to 200 and the event ID to 0 too. And leaving the H/V Trigger as is.
Sorry if I come across as grumpy; it's just one of those days again.
It's alright, I can just imagine frustrating it's been for you but here's the good news, your suggestion for setting the Colon Event to #0200 has worked. The entity moves and works as intended. Thank you so much for your help Charlie.
