This is not from marketplace.

Although it is not from the official Marketplace, it is created by someone in the "community" (other than yourself). Please contact the creator to find out if it is even expected to work with Bedrock since you say it is for Java. If there is an issue that the creator is unable to fix, they should report it themself.

This is actually for bedrock it's just a ui pack to make bedrock look like java.

I am also in trouble with such a bug, please fix it as much as possible (sorry if it is impossible)
