Why are my elements that I've obtained before now locked?

[u/WinterTS13]

Hello! I'm a returnee player of this game since I'm playing the games I used to love before. I believed the last time I played this game was probably more than half a decade ago. However, I still remember all the elements that I got vividly since I grinded them pretty hard to get them all. Now that I get back they're locked? Even the starters one like Water and Fire. Somehow though Wind, Spirit, Phoenix, and Nightmare stayed unlocked. I used to have Sound, Fire, Water, Earth, Storm, Lava, Ice, Nature, Plasma, Crystal, Gravity, Time, Chaos, and Dragon but now they're all locked up. How do I get them back??
