It looks like when the skin was built, the margins were adjusted just enough to push the English text "All Programs" off of the start menu. However, in French, that phrase has more characters in it and isn't completely moved out of view.
I bet you can fix it like this:
1. Open VectorCell in SkinStudio
2. In the tree on the left, navigate to Start Panel -> More Programs Panel -> Background (click on Background)
3. Now look over in the Attributes pane on the right side of SkinStudio. Click on Content Margins.
4. Decrease the left content margin until the text no longer appears and things look properly aligned. Judging by your screenshot, I'd guess setting it to -134 would put it right where it should be.
