Can't update Opencore

The title says it all, even though I update every file in BOOT, OpenCore/Drivers, OpenCore/Tools and OpenCore/OpenCore.efi, when I boot it says that I have 0.6.4 even when I update to 0.6.8 with the files that I wrote. What might be the reason, what am I missing? Thanks in advance!
