So you've managed to connect your Ledger and Ledger Wallet Bitcoin Chrome App, you check address in "Sign Message" option and that address is not shown even there+it is not shown with iancoleman tool also. The conclusion is that the address on which your bitcoin is located is not generated by seed you are using. However it is strange that you see your BitcoinCash coins with the same seed...

Maybe the problem is that you have more than one account related to Bitcoin and you need to learn how to manage those accounts. I will post link to that content, just take time and read step by step : Manage multiple Bitcoin accounts
