Thanks for the file, it's very helpful. I can see the issue is related to the Y Sequence counts. On the Y Axis, row #1 is the bottom and row#2 is the first default segment. Therefore to compensate you need to increase the count for the existing first input to 2
I also noticed that there were a few alignment issues between the glass and the frame. To fix this, change all the segment's Alignment > Z
property to Pivot
I hope that helps, please let me know if you have any further questions.
