Good morning,
If you adjust the line-out settings in a registration and save them in the registration itself, for example Bank 1 - reg 1, then you must also save the registration bank itself when you are completely finished, otherwise it will not remember it.
I work in my studio with the T5 and have the following setting:
Arranger - main out l/r
Drums - sub 1
Bass - sub 2
Right 1,2,3 - sub 3
Multipads - sub 4
I use the Yamaha Registration Manager for this, among other things.
Very handy program, where you can enter and save all settings in your registration. After this, all you have to do is load it into your T5 and everything will be ready as you programmed it.
