Problem with the price during creation of PO?

Hello,i hope that u are fine ?

i have an issue with the price during creation of PO.

first i have a contract ,juste we have a new price with the vendor,so i decided to add another price with another validity period in item post/conditions after that i saved it.

in ME01 i use this contract as a source fix.

after that while i am creating the PO it gives me the price of info record .

is there any solution to solve this issu .
