The Missions are the same for all accounts.
This article on the “unofficial wiki” has a list of all the Missions Available to players.
What I think has happened is that you have cleared all the early missions & just don’t fully remember doing so/ collecting the rewards.
It’s worth noting that the TIERED missions only show the current one (not all of them). So things like the Advanced Iron Mine & House ones will not appear until you have done all the regular Mine & House ones…
If you are SURE you haven’t cleared the missions I would raise a support ticket by contacting game support (see HERE for how to do that)
