Well I clicked edit, because i was trying to see if I could make my scheduling more realistic, but I found out that was the only show that day. i think i left the dropdown on a blank instead of the IL show, so when i hit ok, it was gone. I'm not exactly sure, though.
Edited to include double post. Please pay closer attention to our rules. 
Ok, now it told me I only had 26 shows, and let me pick another one.
