Malakir Cullblade & Tainted Remedy bugged

These cards of Liliana don’t work properly:-

Tainted Remedy.
When I play this support onto the game board it only traps 3 instead of 5 and it deals 2 damage from my opponents cards instead of 1. Also, a number 2 instead of 1 shows on my cards but nothing is added to them, they just remain on the same amount.

Malakir Cullblade
When I summon this card, it starts off with 3/3 and is supposed to gain 1/1 when an opponents creature is destroyed, but when an opponents creature is destroyed, nothing is added to the card.
The very first time I used this card it worked fine for the first couple of destroyed cards, then it just stopped adding 1/1. It hasn’t worked again since.

I emailed support about Tainted remedy and they said that it is a known issue and they are working on it.

Do you know when these bugs are gonna be fixed please?

In fairness, tainted remedy is supposed to heal damage, not grant buffs, but yes, the card text does not match the observed effect.
