Clarification on form 26as

there are the following colums in 26AS Form

Name of Detuctor: 

TAN of Detuctor:

Amount Paid and Credited

Total tax Detucted 

Total tax deposited

Now my question is If the name of the detuctor is a BANK. I see Amount Paid/Credited = 45000/-

But total tax detucted = 0 Total tax deposited = 0.

What does this mean?
