The 1st discovery bonus isn't shown on the sell page - it is applied when you sell the stuff though. I checked it several times when I sold my data on Saturday. Easy to check: take a note of your credit balance before selling a system you're positive you get some 1st discoveries, calculate how much the balance should be based on the system value shown on screen and compare that to the actual value after selling the system.I did that after my first trip, but it wasn't even possible to sell a page then. I ended up with a list of 10 systems that came to about a million. And that was before we had either the 50% first discovery bonus or the subsequent doubling of profits.
