Remote control

Hi all . We picked up our new 2015 Cougar 28sgs fifth wheel last week and it came with a remote control for some items , such as slides, awning , leveller and outside lights. Now i thought that the docking lights were supposed to turn on with the remote along with the outside light that is above the door but it doesn't, I was sure that it came on when I first tried it and also when the pdi was done , but it is one of those things that seems to escape my memory when we went through the whirlwind of thoughts when we picked it up. I have tried every way possible to get them to come on with the remote but to no avail they will come on with the switch on the outside but not the remote. Is this something new ? or am I just an idiot and am doing something wrong? or could there be a problem with the remote/ receiver. Thanks
