I already submitted this bug in-game and was advised to make a post to increase visibility.
When the Grand Nagus Bundle was released, I claimed it on my main character (a TOS Federation character) and had no problems, she got the ship and outfits just fine. When I went to my other characters to reclaim the outfits from the promo section of the C-Store, I immediately began to experience an unusual bug that prevented me from reclaiming the outfit box on half of my characters, it seemed to primarily affect the ones at max rank (it didn't matter what species, gender or alignment). After clicking "claim", I would get a message telling me "Unable to complete transaction: that item cannot currently be purchased" and the outfits wouldn't be deposited into my inventory. Yet, whenever I would log onto my lower level characters (ranks 35 and below), regardless of alignment, they could each claim the outfits fine and in the case of KDF/Romulan characters, get the appropriate "you don't meet the requirements" for the Ferengi outfits when they were deposited into their inventory.

You might need to have fully completed the Tutorial section for that character.
If you're anything other than KDF or Starfleet 2409, you may have more missions needing played.
Addendum:
Well, the character I was talking about above was able to claim the outfits right now (I test it out every day when I log on) alongside another character. Went to other characters to see if maybe the issue resolved itself, but it persisted on the others.
For example, a TOS-era character can use the captain-boost from the Z-Store to get to level 65 but until they complete the missions:
