Assets field inside grid inside fluid

I’m having an issue where I’m using Assets (EEharbor) inside a EE Grid, inside an EE Fluid field. I think I have the tags correctly set up, it’s outputting the correct number of results (files) from the assets field, but all the rendered tags have the same content.

Has anyone encountered this before? This is my mark up.

{cf_fluid}     <!--Fluid -->
    {cf_fluid:cf_fluid_downloads}  <!--Field inside Fluid -->
         {content}
            {content:file_downloads}  <!--Assets Field inside Fluid Field -->
                {content:file_downloads:title}
            {/content:file_downloads}
        {/content}
   {/cf_fluid:cf_fluid_downloads}
{/cf_fluid}

Any help would be most appreciated.
