According to the pop-ups for the two options I meet the requirements for these buildings to be placed. In fact it allowed me to place them during the turn, it just failed to place them during turn resolution and I lost my investment.
I would say this has happened for at least 80% of my attempted colonial placements for trade posts and missions. It’s possible none at all have been placed, but I hadn’t paid close enough attention early on in the game until it became apparent they weren’t being placed, so I can’t be 100% sure none at all have been successfully placed in my game.
