updating reserves bug

[louisholley]

user johnr encountered an issue where they couldn't update reserves for a token. they sent the below screenshots when updating the reserves for their token - the edit button remains greyed out despite having altered the reserves multiple times, no useful error messages/hints are shown.

need to look in to the validation logic for this form and investigate how this may have happened...project in question if it's useful: https://www.fxhash.xyz/generative/25625
