This is a common problem, and has been discussed recently - check the 
archives for the thread "Ignoring certain channels from certain 
inputs".

You almost certainly have a second transmitter (probably a local 
infill, or perhaps a more distant main transmitter in a different 
region) which you can pick up signals from. On a full scan, you will 
get all the multiplexes listed from both transmitters.

The trick is to figure out which is your "good" transmitter, and scan 
a single frequency to get that mux and the related transports (that's 
a tick box you need to turn on). Then you can "scan existing 
transports" to get all the multiplexes from just the one transmitter.
