Single Player - game does not count correctly letters found

Close the game down, Edit: and go into Origin and find Battlefield V. Click the cog icon and go into game properties. Click 'Cloud Saves' at the top, and untick 'enable cloud saves'. This will stop Origin from auto-syncing your details to the cloud copy. Next, open up your My Documents folder. Navigate to 'Battlefield V', then 'Settings' - the full file path is:C:\Users\\Documents\Battlefield V\settingsGrab all of the files in there, there should be 6, and move them to your desktop or somewhere else safe to keep them for later. These files are your user 'profile', which contains all of your settings and certain details regarding the singleplayer.By removing these files you'll force the game to regenerate new copies when you reboot the game. Note that this means you'll temporarily lose all of your settings, and you'll have to replay the 'introduction' mission as well. YOU ONLY NEED to complete the ones you are currently missing. Once you completed the missing challenges or letters check your armory and you should have The Machete skin in your armory. After the skin has been added to your account go back to the new files, delete them and replace them with the files you saved from earlier. I hope this fixes it for you!
