Water coming out of black flow preventer on only 1 zone

Hello I'm new here. I just finished installing a sprinkler system in my house and when I turned it on, everything seems to be working great except for 1 specific zone. Everytime this zone gets turned on, the water starts pouring out from under the bell of the backflow preventer. And its always the same exact zone. I did a lot of research and saw a forum from years ago that described the same exact scenario and they were suggesting that, the pressure loss from that specific zone is causing the water to leak but didn't have a solution. Any suggestions thank you?

Try moving that zone to the number 1 position.

I've tried reprogramming my timer to were my zone 1 will be the 3rd, one to go off but no luck. Its always the zone 1 that makes the back flow preventer leak water.
