Questions about wheelspins and forzathon

Do clothes and emotes get removed as I win them or do they stay?
Seen someone mentioning that they can’t win duplicate cars (cars existing in garage) from spins, they receive nothing when spin lands that specific car. Is that intentional or a bug?
Forzathon daily challenges are not resetting properly, devs aware of that? Is it hard to fix, definitely impacts the experience.

Also, not a question but its impossible to get the reward of Holyrood Park Trail.
