I know this is old but I think I was having the same issue in Office 2013.
I have copy-pasted that spreadsheet into Power Point so that the simulation can (hopefully) be performed without leaving the slideshow and opening Excel.
If I switched to normal view, it pasted fine in ppt with the correct column numbers. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
If you switch back to a different page layout in excel and then update link in ppt, the extra columns will come back. Would you like to answer one of these unanswered questions instead?
If you acquire the box you can drag it to resize the visible area of the spreadsheet.
Then click outside the box to return to Powerpoint.
