Help with unlockable modes.

[YourImagination]

So I am currently re-learning coding and creating with IKEMEN Go. So far, my screenpack is coming along well; logo, intro, main menu and all. I've been experimenting the shop module for a while and thanks to CD2 I learned how to utilize it for stages and characters. So I decided to add in a customer section for game modes.

My issue is the fact that Boss Rush (named "Power Heroes") appears in the  shop but It is still showing in the main menu. At first, I tried to use the unlock code from the shop menu but it shows this instead.

I looked into it more via CD2's regular video and figured out that the system.base DEF file tells me how to make game modes unlockable.

I tried it and it still shows. I decided to take the whole system out and put the shop unlock code in after the "=" parameter. But I got this error message.

Error log:

What am I missing? Here are the codes I am working with. If anyone can help me, it would be great.
