You have a L1 genesis address, so your Available Balance is 0 MNE

You do not yet have 32,000 MNE.  That is the maximum amount that can be self-mined once you upgrade to either L2 or L3.

Once you upgrade you can unlock roughly 2 MNE per day.  It will take about 40 to 50 years to mine the entire 32,000.
