Scheduling issues

ok, so i am going through my schedule in the fleet managment part. i come across several issues like this

plane 1

fll-cvg

fll-msy

fll-iah

iah-fll

then i checked my flight plan, it is all green and it has flights going like this

fll-cvg

cvg-fll

cll-msy

msy-fll

iah-fll

fll-iah

are my staff mad at me so they are not doing it correctly or is it a glitch? 

a screen shot would've been more helpful...i dont know the answer to this problem

MSY-FLL

IAH-FLL

FLL-IAH

FLL-CVG

Maybe it’s a typo but by the looks of it you have a flight arriving at fll, and departing from iah?
