I'm not sure why it outputs it differently from my Display function. If I cout from my Insert function it shows the information inside the node just fine, but when I call Display in main it shows those symbols and stuff. Any ideas?

Seems like some sort of memory corruption. Are you sure your "end" pointers are pointing to NULL?
Please show your entire code.
