Custom Blocks fail to load if register_to_creative_menu property is set

All custom blocks that are registered to the creative menu fail to load with following error.

[Blocks][error]-block_definitions | C:/Users/%USER%/AppData/Local/Packages/Microsoft.MinecraftUWP_8wekyb3d8bbwe/LocalState/games/com.mojang/minecraftWorlds/NM5DXvP4AAA=/behavior_packs/FC_B | blocks/block_acacia.json | description | register_to_creative_menu | child 'register_to_creative_menu' not valid here.

I have attached the block file from this add-on and i have found some what of a work around to get it to work until it is fixed.

if you remove the property "register_to_creative_menu" from the description the blocks will load and function properly. (they will not be in the creative menu but they will be available for /give commands and everything else)

I hope this gets resolved quickly as it does make it much more tedious to test custom blocks.

Thanks
