UPDATE: duplicate of https://www.dndbeyond.com/forums/d-d-beyond-general/bugs-support/134296-racial-features-wearing-belt-of-giant-strength

____

Steps to reproduce:

1. made a level 10 character
2. clicked edit, deleted current class
3. picked fighter level 10
4. clicked change race.
5. Selected earth genasi
6. Went to attributes
7. Selected standard array
8. Went back to point buy
9. Selected +2/+1 bonuses
10. Tried to find Strength in the dropdown menu
11. It didn't appear in the list of attributes

Since whenever I try to take a print screen the dropdown disappears, I did inspect the source of the page:

this happens with this character: https://www.dndbeyond.com/characters/78310967/builder/home/basic

update: the error is due to attunement with a belt of fire giant strenght. Once I remove the item, it works fine
