I decided to go ahead and use my Loyalty Box for the Loyalty Tome and saw this on the screen:

Note how close "Delete" is to "Use on Ula". Ula is my main pet and the one I train. I'm incredibly use to just opening up that screen and hitting the first option. Thankfully I took a moment to look closely at the screen and saw where the "Delete" was located. I would have been pretty upset if I accidentally hit delete.

I'm pretty sure this is not by design. Hopefully you are already looking into correcting this.

This is exactly the same for the Armored Egg and really could do with changing!

Maybe it applies to all non-sellable items?

I seem to remember the loyalty box itself having the same trouble, and that was fixed a month or two ago, but yeah, it looks like it could be the other non-sellable items that still have this problem :(

I just checked the Armored Egg in my inventory, and that certainly still has the delete and first use option side-by-side.

The same goes for any boxed gifts that went into your inventory before the Gifts page was created. I still have like 30 giftboxes that I got long before gift boxes started going to the Gifts page instead. The Open and Delete links are right next to each other

Yep, the still has "delete" and the first "use on" option side by side :(

Can't confirm for the loyalty box item(s) though
