"People you may know" window on my linkedin account

For some reason, there are a lot of people from a same company popping up in the "People you may know" window on my linkedin account in the past two days - almost 100% people in the window from the company. Any idea? I don't have any connection to the company - there was an inviatation from the company two months ago but I haven't accepted it and don't plan to accept it. I had invitations like this before but never observed the same situation from the window.

Could you please share your experience or thoughts?  Thanks!
