I started my own guild the other day and decided to do our first guild mission today. The timer was still active for the quest, but my kills weren’t counting towards the mission. It kept saying “Contract expired. Unable to contribute to the guild mission.” So I forfeited the mission and tried another one, but again my kills weren’t counting and the same message appeared. I have no idea how to fix it. My guild mates are able to do it just fine, but for some reason I’m the only one having the problem. Any answers? 

Contract expired means your contract is expired and needs to be renewed. Being that you're the gm, that means you'll need to renew yourself. Go into the guild menu, select guild members, then click on your name and view your contract. I'd suggest giving yourself a 365 contract so you don't have to deal with it for awhile.

I have same problem, all the contracts is active how do you solve this problem?
