Is this normal? Yes!

I noticed something last night that seemed a bit odd that I didn't notice before. I have a long delay in the delay slot and a short delay in "mod" next to it. I had the short delay ON (in the mod slot) & incorrectly thinking I could quick adjust the delay with the quick knob, I turned it and the delay in the delay slot turned on. At first I wondered why the delay got long all of a sudden then I realized what was happening. If you turn the delay quick knob, is the delay supposed to come on in the delay slot?

Thanks I wanted to make sure this was normal.
