After some research, I found a solution by updating the database.
Each of the Text format mapped fields has a table on the DB, for example:
node__field_sf_implementation
and that table had a column for the format called field_sf_implementation_format that was set to NULL. By running the below sql command, I updated it so it rendered to my needs (I used full_html, but also tested with basic_html; do also note I had to clear the drupal cache for the site to render the articles with the new format).
UPDATE node__field_sf_implementation SET field_sf_implementation_format = "full_html";
@Rishi Kulshreshtha, I have created a Salesforce mapping but I'm not able to find the file salesforce_mapping.salesforce_mapping.mapping_id.yml (or anything similar, recently created). Would you be able to point me on the right direction?
Thank you in advance!
