SBI Bank Account Balance is showing as NOT AVAILABLE but Avaiable balance is showing actual amount

Hello Experts,

I have one account in SBI Bank in a Branch in Kolkata. For last 2-3 years there was no transaction made.Now when I transferred money to this account from another bank  and checked the balance from one ATM ,the transferred amount is shoing as Available Rs. but the Account Rs. is showing as ‘NOT AVAILABLE’.

What could be the reason behind this. I think ideally the transferred amount should be shown as Account balance.

Please help with the possible reason for this. Thakns in advance!!!

Thanks & Regards,
