Export generates empty rows

[shopwareBot]

Steps to reproduce:

• Set up a product comparison sales channel.
• Edit the default twig template (e.g. Idealo) and wrap IF-condition around it, making sure that only products - out of your pre-defined dynamic product group - that met this condition are exported.

So your template should end up looking like:

{%- if product.customFields.zusatzfeld_option is defined and product.customFields.zusatzfeld_option is not empty and product.customFields.zusatzfeld_option != "0" -%}

{#- Default Template starts here -#}

"{%- if product.categories.count > 0 -%} 
    {{ product.categories.first.getBreadCrumb|slice(1)|join(' > ')|raw }}{#- -#}
{%- endif -%}",{#- -#}
"{{ product.manufacturer.translated.name }}",{#- -#}
"{{ product.translated.name }}",{#- -#}
{% set price = product.calculatedPrice %}
{%- if product.calculatedPrices.count > 0 -%}
    {% set price = product.calculatedPrices.last %}
{%- endif -%}
.
.
.
{%- endif -%}

Unfortunately, this generates empty rows in the export file, see screenshot attached.
