Cannot get Base Mode and placeholders working

The Basic method provides ONLY the selected field's data as {{ context }}. The tokens you are adding in your rubric do not appear to be valid Drupal tokens (they should be prefixed with the entity type, as in [node:field_model] so there is nothing that can turn these into values.

I would say that this is working as expected: the Basic mode is - as the name suggests - a basic method that does not support complex data structures: you SHOULD be using the token method for a set up that is this complicated, and if you have issues with the translations of your tokens that would be the issue you'd need to resolve.

Thanks, @mrdalesmith → that's great advice and I suppose it make perfect sense that the Base Mode is just that.

As I eluded to, the Advanced Mode (Token) mode works well but it has limitations and I will try to be specific about them and write them up in separate issues.
