Hive Engine Pending Withdrawal - I have never experienced before

I tried to withdraw small balance of hive to my wallet from swap.hive in hive engine wallet. I have never found pending withdrawal but today, the pending withdrawal took place.

Is this case a normal situation or a bug. I hope if you have the same experience , you can give me suggestion. I also made transaction with blocktrades. The transaction failed when I used hive signer. Then I sent a small amount amount of hbd via hive wallet. The transaction was successful.

I hope the transaction in hive-engine will be normal. I think pending withdrawal become obstacles to get quick fund from hive engine. Thanks for reading, I hope you can give me feedback to the experience.
