A question about confirmed/unconfirmed shares:

1) I have 3.01 unconfirmed shares, currently mining Zcoin. Does not matter how long I mine, a week or two, these 3 unconfirmed shares stays unconfirmed (actually they grew from 2.65 to 3.01 even in one week period). That means later, IF I stop mining current coin which I am mining, then these 3 unconfirmed shares will stay unconfirmed as I have to mine to get them confirmed.  That means I loose money.

I find it really weird. Can anyone explain me how to make unconfirmed shares zero (all confirmed, balance zero??):

Thanks
