Hi,
You said the problem appears in the last line, so I guess you are telling about the horizontal alignment of the elements in Mini Page 'pps_50', right? This problem is due to property 'Y-size' set on both WordWrap boxes 'WordWrapBox40' and 'WordWrapBox42'. The other WordWrap boxes of this container don't have 'Y-size' set. If you unset 'Y-size' on both elements above (clicking on the 'reset' button), the problem should disappear.
Actually, you should't set a 'Y-size' (height) on a WordWarp box, because the element should typically grow according to its content. If you set a fixed 'Y-size', you'll forbid that automatic enlargement. In your case, you combine WordWrap boxes having 'Y-size' set and WordWrap boxes having "dynamic" 'Y-size'. The baseline alignment will be badly interpreted in this case and will drive to bad horizontal text alignment.
Now the behaviour might be a bit unexpected. We'll have a deeper look on this...
Thanks.
Best regards,
Romain W.
