PBS Dependent Visa ( Tier 2 General Visa)

Hi Everyone,

I am the main applicant on Tier 2 General Visa ( 3 years or less). Me and my wife we both are applying together. She is applying for dependant visa.

In my completed application form (after paying fees), it shows

TYPE OF VISA / APPLICATION: Tier 2 (General) visa

Whereas for my wife's application, it is showing the same line as empty

DURATION OF VISA:

I have checked that I have filled her form properly and have mentioned my details as well in her application.
I am confused why the duration is not mentioned. For one of my friend's wife's visa application it is mentioned properly as "3 years and extend" but the thing is he applied for his wife to join in UK ( He is already in UK)

Is it because we are applying together and duration of her visa will be same as fine once granted.

Please help!
