I keep getting the same voyage?

I just recently started play a day ago. The game told me to do to the hoarder and get the free voyage that I'm assuming is the tutorial one (assuming) so I finished it and my friend sold the chest. But then as soon as I got back on the boat it said to get the same one that I just completed. So I did it for a second time and after I completed it, it me get the same voyage for a third time. I don't know if it's bugged or not but it's really annoyed
