Missing travel signature in i20

[gc2016_2]

Hi, my employer is sponsoring me for an eb1 based application. While I am gathering some documents, I noticed that one of my i20's is missing a travel signature for a previous year, which is 10 years ago. These are on 3rd page of the i20's, if you are not familiar with it. But their first pages are all signed. Would this create a problem for i485? If so, what do you think I should do?

Thank you dearly.
