Pull From List throwing unintended results

As shown in below image

In Pull from List called Is there Item? Request Number is 2 and Require Number is 2.

Here doubt is

When in List, only 1 item is available and when token arrives at Is there Item? and tries to pull from the list , the token is failed and enters into failed loop but still the item is pulled from the list. I'm attaching the model for reference.

Since your Request and Require values are 2 and your Max Wait Timer is 0, when the transporter arrives to the control point and there is 1 item available, that item is pulled. But because there weren't 2 the wait timer expires the puller "fails" because it didin't pull 2 of the Requested/Required amount. This is the expected behavior when using the Max Wait timer. What are you hoping to have happen?

@Regan Blackett Thanks for the feedback.

Actually what I'm trying to achieve is

I'm trying to Pull 2 items, if only 1 item is there then it should not pull that one 1 item and it should fail and should go to fail loop. Is this possible to achieve?

Check the "All or Nothing" box on the pull activity.
