PHOENIX LOG NOT UNLOCKING

Hi everyone. I’m hoping someone can help me with this issue.

I’m having trouble unlocking a phoenix log in Awakening the Nightmare during the ‘Light the Fuse’ mission. It’s the last phoenix log I need in order to get the Brute side achievement. It’s listed as the ‘Tread Carefully’ phoenix log. Whenever one of my units passes over the phoenix log, it gets picked up but the game does not register that I collected it. The achievement does not unlock and when I go back to the main menu it show’s that I have not collected it. Each time I play the mission I can pick up the phoenix log on the map but when I exit the game the ‘Tread Carefully’ log entry still shows as being locked.

I’ve tried restarting the mission several times now on all four difficulties. I’ve played the mission through until the end and it’s still doesn’t unlock. I’ve reinstalled the game and DLC and that hasn’t worked either. I’m playing on the Xbox One. I’m hoping that this glitch will be patched in the future.
