Weapon attachments unlock bug

On several weapons in the beta week one and two I have had weapon attachments fail to unlock when reaching the required mastery levels for those attachments. That still have a padlock on them and are greyed out as if you have not yet reached the threshold to unlock them this is the only bug I have encountered that is not already listed in the known issues hope to see this fixed by release as it’s a big letdown to work towards a few wanted attachments on your favourite weapon to then see your not going to get it and then have no workaround to force it to rectify its self I.e rebooting the game etc
