Enchantment isn’t fully working
Several times while playing, I’ve used an enchantment that is supposed to restrict a card from attacking, blocking, or being able to use their abilities.
Several times however, the creature’s passive abilities were still triggered, allowing them to still utilize its abilities to buff other creatures.
As you can imagine, this can be huge. Several times I lost because I thought I neutralized the card’s abilities only to find out too late that even though the creature can’t block and attack, somehow it’s abilities are getting triggered

They're working fine, you're just not understanding the enchantments' ability blocking part.
The enchantments block activated abilities, the ones that have a cost of some sort to be paid.
They do not block the triggered, or passive as you say, abilities that happen automatically whenever something occurs.
