The reason why you're getting this "array" on the frontend is because the field data is stored as a serialised array in the database. Given that you're using some dynamic field option to pull the data from the field then it won't work. The template builder that you're using isn't going to format the array of terms so that they're readable.
To resolve this you will need to use our Toolset Types shortcode to display the information from this field. An example usage is.
[types field='field-slug'][/types]
Replace field-slug with the actual slug of your custom field.
For the images, this appears to be an issue with the page builder because when I edit the page using the page builder the correct images show up. So you will need to contact the support team for the builder for them to debug this one for you.
