Bigg Boss Telugu 7 update, September 18: Shivaji nominates Amar to save Tasty Teja

The weekly nomination process of the Bigg Boss Telugu 7 house is a customary ritual that happens every Monday. A total of 7 members were nominated for this week. Here, Bigg Boss gave a special power to Sandeep & Shivaji, which changed the whole scenario of nominations.
This power is all about saving one person from the nominations and nominating one person from the safe contestants.This decision needs to be taken by Sandeep and Shivaji jointly, as they both hold the Powerastra in the Bigg Boss Telugu House.
Before Bigg Boss announced this special power, a total of 7 members were nominated for this week. They are Priyanka Jain, Gautam, Rathika, Subha Sree, Prince Yawar, Damini, and Tasty Teja.

As Bigg Boss instructed to save one person, Sandeep-Shivaji saved Tasty Teja from the nominations. When it comes to the nomination, they nominated Amardeep. This decision surprised the audience and also the contestants in the house.
Coming to Teja's save from nomination, it is expected as they both are very close to him all the time. But, when it comes to the nomination of Amardeep, it raised many eyebrows. Amardeep questioned Sandeep and Shivaji for their decision and asked the reason. They both said - you are a strong contestant and would be safe in the elimination process. Amardeep wasn't satisfied with their version, but he hasn't got anything to do here.
After this decision, Amardeep replaced Tasty Teja in the nominations, and now it may trigger tensions between him and Sandeep-Shivaji. Well, if we see the nominations for this week, we can say Prince Yawar is slightly weakest among the others. His language barrier is the main hurdle in the Bigg Boss House.
What's your opinion on the decision of Sandeep & Shivaji? Are they correct?
