I am getting false timer conflicts with a program that is scheduled just after midnight ( V8 Super cars highlights) and no other programs within5 hours of this one.
Firstly check the actual Humax schedule to see if it is set to record. We simply report back what the Humax tells us and sometimes their tuners get in a knot if programming is changed, but as you only have one recording at that time it may well be set. If so simply ignore it and all will be OK going forward. If it isn't set then try doing it again manually with the remote control and, if it then sets, after that problem time has passed it should be OK.
