You arrived from Slovenia, which, like Germany, is in the Schengen area, a group of countries which have largely abolished border controls between each other. For the purpose of border control, you were effectively on a domestic flight.
You'll go through (exit) passport control when you leave the Schengen area. Here they'll check how long you've been in the Schengen area as a whole - which exact countries you've been isn't important.
