Hi! I had this happen as well. I figured out it was because we have a label added in our task tracker integration. Because of that label, even if I delete that request in procurement, it appears again because that label is still present in the task tracker. If I have a procurement request that ends up being canceled, I just archive it, then it does not reappear. Hope this helps and is not too confusing! Dm me if you need more clarification on my end.
