Welcome to our Forum 
You are almost certainly doing nothing wrong…
It is the broadcaster(s) not using crid codes (series/programme link codes) correctly – eg C5 and Quest
I have to remark I have found C5 a total mare since they have moved to HD on Freesat/Freeview. I have duplicate progs being recorded at all times of the day and night. They have never been perfect but I think they have now given up any pretence of bothering.
