Canning help

[Chiefster23]

Fellow home canners! I need some help. I have been canning for years and I have never had any spoilage, thank heavens. But i do have problems with losing liquid inside the jars. Yesterday I canned 6 jars of garden veggies. Two jars turned out perfect. Two lost some liquid but nothing extreme. And two lost a lot of liquid. I have always had this problem and i don’t know what i am doing wrong.

I do expell all the air from the jars before installing the lids. This year I bought and started using the ball torque tool for installing the bands so I’m pretty sure the lids are on properly. So what the hell am I doing wrong? Yes, I also follow the ball canning guidlines about correct headspace in the jars. I have and use the tool to measure airspace. After pressure canning, I allow the pressure to come down naturally and I allow the jars to remain inside the canner for another 5 to 10 minutes after lid removal before removing the jars from the canner. Help!
