Why do I have to do the wedding quest again after I finished in time Sims mobile

[18142111]

I finished the quest and did my next generation ( aka the baby's into adults) and I wanted my girl to get married and I had to do the quest again with the same quest reward is this a glitch?

@18142111 Did you claim the rewards from the quest the first time you completed it?
