Issue with "Storm of Steel" Achievement Not Unlocking - Battlefield 1

The achievement in question is Storm of Steel. According to the requirements, I need to complete all Codex entries in the "Through Mud and Blood" chapter. I have checked, and I have indeed fulfilled all the necessary conditions for this achievement. However, the achievement has not unlocked for me.

I am unsure what to do next. Is there there a common fix for this kind of issue?

Specifically, I have read that sometimes deleting the local save data and trying again can help but noting happened.
