Double WYSIWYG Fields

I have some custom gutenberg blocks with mb-blocks, and they are being declared like below:

        'fields'          => [
            [
                'type' => 'wysiwyg',
                'id'   => 'title',
                'name' => 'Title',
            ],
            [
                'type' => 'wysiwyg',
                'id'   => 'text',
                'name' => 'Text',
            ],
]

However it seems that on the frontend I'm getting 'double' the WYSIWYG. It's quite weird and I cannot figure why this is happening, as it happens only on page load. If I click out of the block, and then click back in, it's ok and not double.

Anyone ever encountered this before?
