How to fix window level in milestone window?

Question

I have 12 windows in home. Window is "milestone single hung 1000". So already ordered and replaced. Channel balance(S380-29, 2840option), top sash guide(1/2", 18-180), window sash lock(2-1/4", 90-005). I installed all window parts. All window is working well. But I got just only 2 window problem. As if pic, the left window put down perfectly, but right side window is not put down perfectly. In Right side window's top, It had not much gap and bottom area had gap. I try to push down But I can't. So about top area's sash lock, I cound't insert lock perfectly and no lock. To try to fix, I exchange channel balance and window both(right-left) but I can't resolve. Same issue.

Pic1(window),pic2(sash lock),pic3(top area:no gap), pic4(l-r level), pic5(right bottom gap). Please give me good tips. Thsnks

I'm not sure exactly what the problem is. If I'm following, it sounds like you bought a few S380-29 balances and installed them in two windows. One window works fine, but the other window won't close.

My first thought is that the balances you bought weren't right for that window. Did you double check to make sure that the S380-29 2840 balances were a match for what was originally installed? Let me know if that's the case and we can work from there.
