Topic: Ghost of Tsushima save file problem

So I downloaded Ghost of Tsushima Deluxe edition on Ps4 when I got the seven day Ps Plus Trial. I played the game for about 5 hours, liked it a lot, then the trial ended so I went out and bought a physical copy of Ghost of Tsushima but not the Deluxe edition. I played until about half the game using the same autosave I already had, no problems, but several days later I die to an enemy and the game says it cannot load the save file because it is a Deluxe edition save file.

Does anyone know a fix for this? Thanks
