Big blank space after header when using itmize in 2 pages in Latex

Question

I'm trying to make a document in latex using a table as a header, but everytime I use an itemize or enumerate longer than 1 page, the 2nd page has a big blank space between the header and the listing.

Can you help me identifying the problem? Any comments would be appreciated.

PS I found it really difficult to make tables in latex, so I used a table latex generator.

Answer 1

Most of the additional space comes from the two extra rows at the bottom of the table. There is also an additional column with can be removed as well together with all the unnecessary multicolumns this dreadful table generator inserted.
