ADD STAKE AMount button greyed , cannot stake

Hi. I have transferred my AGIX from Binance to Metamask, my metamask wallet seems to be connected with the AGIX staking app (at least I see my wallet info in it), the staking window seems to be still open but the “ADD STAKE AMOUNT” button is greyed and I cannot stake my agix. What do I miss? do I have to wait for the next “Call for staking” period ?

Thanks a lot for any clue, I want stake my agix.
