Problems while I have to sign & confirm

Hi there!

Hopefully someone will be able to help
I’m tryin’ to stake some ones, transffered them from Binance to address. I can see all of them. Can also see them in Harmony One Mainnet in Metamask. The problem appears when I try to stake them… I simply can’t press the Sign & Confirm button. It appears not-clickable. What am I doing wrong?

Solved it on ONE Discord support channel. Ty!
