Issue:
When trying to open the Colors tab under General in the SUF settings, a Lua error occurs.
The Colors tab loads, but the Classes subsection (near the end) fails to load, and it remains completely empty.

Steps to reproduce:
1. Type `/suf` in chat

2. Go under General > Colors
3. The Lua error immediately appears

Lua Error Message:
```Lua
