For starters, it would've made much more sense to change the air filter before doing the carb balance, because the probable better air flow may change the set up!
The trick with balancing the carbs is patience, and eventually you can get all the rods pretty level on the CarbTune.
For me it's always been 3 & 4 that have been the nuisance to level out, but i do get there in the end and all is good.
I've not really noticed any particular one being extra jumpy before though, but as i said sort the air filter out first then give it another go.
Make sure the engine is up to running temperature before adjusting anything, and do a quick TPS check before and after carb balancing.
