C++CLI bug, stacking trackbars (weird visual effect and crash)

I need help with this crashing and visibility issue with my form. This is a form within a DLL that gets loaded upon startup. I have made a really longwinded post on StackOverflow to try and get a bit of assistance. Here is a link to it:

If you guys could help me by looking and commenting on the post or back here it would be amazing.

Just use the same sliders again and check for the selected index.

Use switch cases instead of if else statements, they have been invented for a reason.

Don't use WinForms in an internal cheat, lol.
