Changing occupations on a ship passenger list #general

Michele Lock

I have the ship passenger list for my maternal great great grandparents Jossel and Michle Leibman and two of their daughters, arriving in July 1906 on the SS Westernland in Philadelphia. On the page that includes them, I noticed that 12 out of the 30 passengers had their occupations changed after the manifest had first been filled out.

The Viewmate image of the entire page is available at:

A snippet of the page is below - 

Some of the changes don't make much sense to me - changing 'Laborer' to 'Druggist', 'Laborer' to 'Capmaker', etc. Almost all the listings for 'Domestic' (meaning a maid) were changed to 'Tailoress'. I checked other pages in the manifest, and this is the only one that has so many changes. By looking at the handwriting, the person who made the changes was not the original person who filled out the manifest.

Does anyone know what the reason(s) for so many changes might be? My impression had been that passengers were not re-interviewed about their occupation or any other details, once they were on the ship. I also assume that once they had arrived, the US immigration officials would have asked them what their occupations were.
