Aircraft's value error

My pending aircraft delivery looks strange. My aircraft values of B767-300ER were set as $1b.

This could influence to the total value of my airlines from $200 billion to $700 Billion.

Please check aircraft value for me.



And I discovered $320M paid for 757-200 also. In my Aircraft page, that was not anyone as 757-200 of values of $100M.

It is why?
