Why did the master commend the unjust steward?

Since you do not know the parable of the unjust steward, here it is. An extremely powerful insight is hidden in this parable.

Also [Jesus] said to the disciples, There was a certain rich man who had a manager of his estate, and accusations [against this man] were brought to him, that he was squandering his [master’s] possessions.

2 And he called him and said to him, What is this that I hear about you? Turn in the account of your management [of my affairs], for you can be [my] manager no longer.

3 And the manager of the estate said to himself, What shall I do, seeing that my master is taking the management away from me? I am not able to dig, and I am ashamed to beg.

4 I have come to know what I will do, so that they [my master’s debtors] may accept and welcome me into their houses when I am put out of the management.

5 So he summoned his master’s debtors one by one, and he said to the first, How much do you owe my master?

6 He said, A hundred measures [about 900 gallons] of oil. And he said to him, Take back your written acknowledgement of obligation, and sit down quickly and write fifty [about 450 gallons].

7 After that he said to another, And how much do you owe? He said, A hundred measures [about 900 bushels] of wheat. He said to him, Take back your written acknowledgement of obligation, and write eighty [about 700 bushels].

8 And [his] master praised the dishonest (unjust) manager for acting shrewdly and prudently; for the sons of this age are shrewder and more prudent and wiser in [relation to] their own generation [to their own age and kind] than are the sons of light.

I will update the answer after a few days. Just want you to do an exercise. Meanwhile ask the Holy Spirit? He is faithful. For a long time I was searching for the answer. But one fine morning when I was outdoor asking the Holy Spirit, the Lord in His mercy & kindness reveled it to me. All the best in your quest.
