Supply Chain - Requisition Approvals

Hello, I am new to this forum. My name is Dino and I work as an applications support in Manila Support Cloudsuite Supply Management. I am new to the technology and somewhat on study mode. I have learned the basics but there are some tricky issues. I have read some documents and did some troubleshooting prior to asking this question I am setting up a requisition approval in our Lab. I have already setup my username as Level1 and Level2 approval. The IPA workflow looks correct and I did not find any issues. It says that the amount, if it is greater than 500 dollars will only go through level 1 approval. If it goes beyond 1000 it will pass through level 1 and level 2. However as I kept on submitting sample transactions to have it approved by level 2, it bypasses the level 2 approval. Once it is approved by level 1, it goes directly to Purchase Ordering or warehouse shipments. I have setup Requesting location, Requestor and Inventory company as Header Approval. Is there anything else I may have missed? Thank you.
