Packs disappear

[King_UTG]

I’ve noticed when I have multiple packs that after I open the first one the rest disappear. This has happened to me on three different occasions

if you have multiple packs and you click "open" it opens them all at once, and shows you one list of cards from all of those packs

Yeah, count the cards.  For instance, if you have five packs, you'll only see one opening animation, but you'll end up with 30 new cards, not 6.
