mjolstin mentioned that I should post my issue here so here it is.

I have a bird that was level 75 (now level 76). I was able to cap once during the Nuri expansion and was able to receive the Shield of Hallows. I have the Eye of Eternity now as well, which is another shield. I was really excited to know that if I have capped twice, I am going to be able to receive the Ring of Valiance. Upon learning that I needed to equip vanities, I felt distraught that I would not be able to receive the ring due to having two vanity shields even though I have capped twice. I feel that it was a futile effort for me to play and try to cap and not be able to receive the ring, and that it is better to just wait until the next expansion to try and cap it. I then read a forum saying that support was able to help someone with a similar situation I had and that gave me hope, so I proceeded to email support to ask for help.
