Missing <g:gtin> Tag in xml generated by Google Products Plugin

-- HikaShop version -- : 5.1.1
-- Joomla version -- : 5.2.0
-- PHP version -- : 8.2.23

Hello

I am currently trying to configure the ‘Hikashop Google Products Plugin’. Unfortunately GTIN is not generated. As far as I can see, this is a bug in the current plugin.

If I assign the same custom field to ‘MPN’ as a test, the tag ‘<g:mpn>’ is output correctly. If I assign the same field to the field ‘GTIN’ in the plugin configuration, no ‘<g:gtin>’ is output.

Thank you for a quick check to see if this works on your side.

A small addendum: A tag ‘quantity_to_sell_on_facebook’ is also output. Can this be deactivated and how? This is missing in the documentation.

Many thanks for your help, Nicolas. So that others can also benefit from this topic: I had defined the values ‘true’ and ‘false’ in the custom field ‘identifier exists’. However, this does not work, the parameters must be ‘TRUE’ or ‘FALSE’ (uppercase).
