Default [Q] 2.3.7 Adrenaline ROM on Galaxy Ace S5830 Calendar Not Syncing

As the title suggests, the Calendar app that comes stock with the Adrenaline ROM (v2.3.7) on my Ace is not syncing with Google. I've searched other threads but I'm not confident that I'm finding solutions for my specific ROM.

Model: GT-S5830
Android Version: 2.3.7
Baseband: S5830DTLKI4
Kernel: nims@ubuntu #7

Does anyone have a fix for this or give me directions on how to fix it?

Please help!
