Hi there,

we are building a custom theme with ACF Pro and block.json. We have set up different blocks with different fields.

Problem:
When inserting a block into Gutenberg Editor, the block is ’empty’, even the default value set on any field is not loaded. As soon as we interact with the block, like changing any value, the whole block loads the values.

Question:
Is there any way to load all values on direct block insertion? Is this even default behaviour or is there a problem on our side?
