CascadeDishwasher Detergent ActionPacs, Lemon Scent, 28 Count

Why is this listed under gluten free? Isn't all dishwashing detergent gluten free?

Is this good for a bubble bath too?

I would like to cancel my order. how do i do this. does not show where to cancel. thank you. i have so many i really need to cancel.

I put into the detergent dispenser and close the lid. When dishwasher cycle finished dispenser door is open but pod hasn't dissolved. What's up????
