1.19.2 Custom Grass doesn't allow flowers or plants to be placed on top?

[eeyorenailbag]

So I've made a few new grass blocks for a mod, and have used the correct block type for them, and even added them to the "dirt" tags, but for some reason they don't allow me to put flowers or plants on them? Stranger still, is that it works in one specific world, and if i load that world, and then another, it works again, but on a fresh startup, any new world still has the issue.

Any ideas on what the problem could be? Thank you!
