Default [Q] Icon Disappears from Dock on Reboot

Hello. I have an original Nexus 7 running CM 11 snapshot M2. I noticed that when I reboot, the right most app icon disappears. It has not ever done this before. It does not matter which icon is in that position. That app is still installed and can be added back from the app drawer but the icon keeps disappearing. Does anyone have any ideas on what is wrong and any remedies available? Thank you.
