That looks different from the output in the first email. There best routes were received not only from ibgp, but from the same peer, so it seems ok that they were not sent back.
For this output you have now session with your ibgp peer eatablished, but it still do not see the routes.
Localpref should not affect exporting directly, yes. It can alter the best route, which will be considered for exporting.

Hello Alexander,

the route is received via eBGP and should be redistributed via iBGP:

The only difference to other routers is that the bgp local preference is
50, but from my understanding it should still be exported via iBGP.
