why is my crimson heirloom pack progress reset?

i bought 7 crimson heirloom packs a few days ago and now it says i have zero collected, i didn't have any of the skins in the collection before buying the packs but now it shows a list of skins i can get instead of the once i just got. the packs cost didn't reset just the progress, the packs still cost 500 coins. i don't see anywhere that says that they are supposed to reset either.
