Unable to unlock achievements

I have been trying to unlock two achievements in PVZ2: Beet It (planting ONLY Phat Beets in a level) and Ragweeds to Riches (planting 5 Gold Leafs in a level).

However, I am unable to unlock both of them. 

I've looked up strategies online but none of them worked. I avoided using plant food, using any sun-producing plant, and I didn't even include any sun producers in my inventory.

I've already made sure that my version is updated, and even restarted my device. I'm using an Android. Been playing this game since 2020.
