Staking AGIX

Hi I came here trying to find out why I cannot stake AGIX on SingularityNet
I have authorized staking escrow contract and my tokens are listed on the page
The “Add Stake Amount” is greyed out so I am unable to stake my tokens
The auto renew button is ticked, but there are no tokens to renew, this is very confusing
do I have to wait until the next session commences on 6th March, even though the current session is open until 13th March??? Regards JEFF
