Problem with build number about flashing

Hello, I wanted to flash my phone to nougat since i don't like oreo atm and it causes problems to my phone.

The problem is, when i go to the spain firmware in XperiFirm, there is only Vodafone Es (where i bought it), but right now my phone has the build number 34.4.A.2.85 and in XperiFirm the last build number is 34.4.A.2.70 .

I wanted to know if when i install it this will cause any problem or if i'm gonna be able to update it later.
