Custom addon biomes not working is a bug of Minecraft Bedrock Edition itself, we are still waiting for them to fix it. I recommend getting in touch with Mojang on more information on the bug and if they plan to fix it. More specifically, check the issue on their bug tracker and comment there if you need more info
What was the addon script engine update for custom biomes then?
"
Add-Ons and Script Engine
Custom biome names are no longer implied by their filenames. Biome names are explicitly specified via the "identifier" property under the "description" sub-object of their JSON definition.
Biome identifiers must now be namespaced (ex: "minecraft:plains"). Client biomes with a format version lower than 1.21.90 will have their identifier automatically prefixed "minecraft:" when loaded if no namespace is already specified.
Updates biome documentation to match updated biome JSON formatting and requirements.
Biomes client settings now look up settings based on the biome's full name, including its namespace. Vanilla biomes will fall back on their name without a namespace if an exact match is not found before falling back on default settings (for example, "minecraft:plains" will match itself, then "plains" if no setting was found)

MCreator is not affiliated with Mojang, so we can't provide you answer to this question. But you can try asking at https://bugs.mojang.com/browse/MCPE/issues/MCPE-100700, https://bugs.mojang.com/browse/MCPE/issues/MCPE-151938 or many similar tickets. Thank you for understanding
I think it would be perfect in the Java block to be able to select the created display item, as I find it a bit silly to have to create a 2D item to represent the block, and then have the item support the display configuration. In the geckolib example, it's possible to export only the display configuration.
I would like to ask again if you could please add a sign/hanging sign base block. I know this wouldn't be easy persay. But... I would really love to have fully finished wood sets. I have asked this many times and searched for any addon that does this but alas I couldn't find any. I know you don't get much out of this service to the Minecraft community. But I would highly appreciate it. I'm not trying to be rude this is just a genuine plea for finished woodsets. I don't want to push it but boats would also be great. So thank you so much for your diligent work on these snapshots.
Signs are essentially an entity, so if we were to add this, it will be likely a separate mod element. Similar to boats. We may add something like "miscelanious entity" in the future for things like boats, signs, and carts. How soon depends on the community support and the number of developers we have at a given time
I think this is the first time I heard of the bug of transparency option dissapearing. Did you report this bug on the correct channels (github)?
