Field values from database not in pdf

I have a form on https://www.allianceexperts.com/distributor-search/ that works perfectly well: visitors can select a country, and based on that country with the plugin CF7 Data Source I retrieve a monthly rate, that I can show on the webpage and is visible in the pdf.
I have made a copy of the same form and put that on https://www.allianceexperts.com/distributors-new-zealand/, but without the Dropdown, using the CF7 shortcode to pre-select a country (the field is country2). The shortcode looks like: [contact-form-7 id=”6c7e8f0″ title=”Costing & Proposal form” service=”ProposalMS” country2=”New Zealand”]
Also here the correct monthly fee is retrieved from the database and shown (€ 1500), but when I generate the pdf, no value is shown where I put [BDprice]. And I copied the whole pdf using a json file from the other form. Other values and selections in the pdf work fine.
What can be the reason here? If the pdf is generated, is there then another database action? How to resolve this?
