Normally I will design the window by make sure all of the length attributes and labels same.
it could be a problem by converting to webaccess. Please "delete Web Access Window" and make it available again.
Then test the Window in your browser. If this doesn´t help, then check your width of the groupbox, labels and the attributes.
If it was my window I would concentrate on the properties value of each of the attributes to ensure they match up per column.
As a starting point what happens when you highlight and drag all right hand column labels more to the left and land them? You may need to save and view in webaccess to see true view. Remember make copies of your windows to avoid losing progress.
You may also want to move the groupbox containing the one attribute of No Billing as this may causing the issue so move it below or hide it temporarily.
I would start by highlighting the right hand column and setting the same starting point, height and width all via properties. Then align each group box again via properties to the one next to it.
Hopefully these steps help alternatively there is a few community articles already around columns and alignment within windows.
