I think you are mixing up things, to be expected as a newcomer. You'll be fine soon enough.

Can you attach the leaflet with the 48 frequencies please.

"Settings" has different contexts. It is usually meant as a premade list/groups of channels.
The configurations/settings are saved in a file called "settings" in /etc/enigma2. They are not identical across images.
The frequencies that you set your tuners to communicate with the LNB are noting to do with the frequencies that the channels are on.
You can scan and then create your bouquets to contain what you want. No matter which image you are using

So maybe an an idea to start again and do things one at a time.

Flash OpenViX
Configure tuners correctly. Zip and attach your file called settings here if you want someone to double check for you.
Scan 19.2. (Manual Scan > single satellite > no to network)
Create your bouquets using E-chanenlizer, Dreamset, Dreamboxedit. Or use OWIF. Or the remote to do it.
