How do I get more consistency in my batches/ am I doing something wrong?

Right one was from my 1st batch from yesterday, left one was from the 2nd batch. Both of them are cherry jam, I used the same ingredients in both. My coworker has mentioned something about cooking it slower, and I tried that with these two but still they varied. As you can probably see the second batch is SUPER bubbly and foggy, which I do not want. I’d like them all to be clear and pretty like they are supposed to be. When I make jelly I never have this issue it’s always clear with no bubbles so I’m confused. I’ve made cherry almond jelly, cherry pepper jelly, and normal cherry jelly and they NEVER end out like this. I honestly have no idea what is happening but I’m not really an expert on canning and do it mostly for work. The person at my work who knows the most about canning and is our main person who does it is on leave for personal reasons so I’m not able to ask her rn. she’s the one who originally said to cook it slower though and idk if I’m still not doing it right. I felt like I did these two batches exactly the same though changing the temp slower and at the same pace. I should also mention the first batch foamed a LOT, the second and third did not though. Idk what makes them foam vs what doesn’t though it feels random and (not the expert coworker) my other coworker said hers are just as random too, just for the cherry jam also.
