Decoders are usually 28/128 speed steps by default. The older 14 speed step is a "legacy" issue and part of DCC history, however its still accommodated to look after older products.
You have to set the controller to the 28/128 speed steps.
Your light problem is happening because the decoder is at 28/128 and the controller set to 14 speed steps. It will go away as soon as you do that.
The FL Twin centre isn't the latest and greatest by any means and programming wise compared to other brands it IS hard to get on with, but persist and those things that are hard now will get easier with practice. There are several FLM Twincentre users on MRF that will hopefully be able to give you some pointers
