Hello,
we have fixed it globally in our code
you may check etheme_product_brands_render()
xstore/framework/compatibility/wpbakery.php
we have moved some part of code below condition if brands exist for product -> https://gyazo.com/c1f37697dafdabdcbf2fdbecca10157c
after this change firstly we check if product has any brands and only after that we will start output brands. Before it we started output but cut it in case no brands were found for product.
Regards
