Huge blank space between end of table and footer/end of page?

Greetings,

I'm having trouble getting rid of this enormous empty space that happened to appear after the end of the table in the first page of my worksheet.

There's no footer, and if I try to set one, I can see that this white space is set between the footer and the table. The bottom and footer margins are set to the lowest non-zero size. I also cannot drag to extend my table down any further.
The orientation is set to landscape.

I'm really confused, any help is appreciated
