Custom Flowers and Crops turn Grass and Farmland into Dirt

This bug has been happening for a while, but I can't quite remember when it started happening so I'm just reporting this as a 1.20.10 bug.

Description

Flowers and crops from addons do not act like proper flowers and crops on Realms. Instead, they act like blocks that turn grass and farmland into dirt after a while.

Steps To Reproduce:

1. Download the addons below
2. Go into a world and make sure the flowers/crops work. You will notice that they let the grass and farmland stay.
3. Put these addons onto a Realm
4. Once on the Realm you will now notice the grass and farmland rapidly turning into dirt blocks instead of staying

Expected Results:

• Flowers should be able to stay on grass without turning it into dirt
• Crops should be able to grow on farmland without turning it into dirt

Actual Behavior:

• Flowers turn grass into dirt
• Crops turn farmland into dirt
