Nature's Calling Event progress same on different platforms? Glitch or Normal?

I have Sims 4 on 2 different platforms: PC & Xbox. On PC I have many packs and on Xbox, few. I played through the Nature's Calling Event only in my PC version, with characters I made specially for the Event. On that version, I found out the hard way, at the very end, that, although the rules state that "optional" quests don't count toward points totals to finish the Event, that is not true if one of the "optional" quests is from a pack you own. In my case, I had just adopted a dog before the quest asked me to do so, and I didn't want to adopt another. I own Cats & Dogs (clearly), BUT the quest said "optional," so I ignored it. However, at the very end of the Event, I ended up 10 points short of being able to claim the last reward item, with no more quests available to earn any more points. 10 points was exactly the amount I would have earned on the "optional" quest I ignored. Having now understood this, I tried to go onto my Xbox account to do the Event with a character I had made for the Reaper Event previously, because she had full Gardening and high Handiness skills and could get through the Event in these last few days quickly. But, when I clicked on the Nature's Calling Event overlay, it showed the exact same progression that my PC character had gone through: Finished Event with last reward item unattainable. How is this possible, with 2 separate platforms? I DO have my accounts linked on EA so they know that both belong to me as same person, but, if packs don't link on 2 platforms, why are Events? I don't want to unlink them, but I do want to know if this is normal or a glitch? There's not much time in the Event left.
