First of all, I'd like to preface this post with praise. I played for a approximately two months around a year ago, came back in May, and have had an incredible time. I fell in love. Stormblood and Patch 4.1 have brought a lot of terrific changes. With that said:

Veteran Rewards: Items you already own cannot be exchanged for. The possible problem with the Cascadier Uniform Voucher is that it allows this (for means of obtaining male and female I suppose). Reading the text on the Voucher, I had no idea what it was, and in a rush of excitement, spent 2 Certificates to get it. While I was still able to purchase everything available, with spare Certificates, it irks me that I have the Voucher sitting in my inventory. There should be a prompt, mentioning that this item is already in obtained and you're purchasing another.

As this is my first post, I apologize for any long-winded sentences. Thank you for your time.
