first_name & last_name & email do not pre-fill from URL query string

Hello Im having an issue with the first name, last name, and email being prefilled.

The custom questions prefill fine from the URL Query String but not the contact questions.

I checked ‘Allow Query Strings’ from the User Strict plugin dashboard but I did not check ‘Prefill User Info’ as it takes precedence.

Here is the Calendly embed code copied from UserStric’s Plugin.
[wpcalel type=”calendly” url=”https://calendly.com/travel-secrets/meeting-details-call” widget=”inline” query_str=”on” min-width=”100%” height=”800px” hide_gdpr_banner=”on” hide_event_type_details=”on”]

Here is the URL where the Calendly embed is.
https://travelsecrets.vacations/go-trip/meeting-invitation-las-vegas/?first_name-joe&last_name-Doe&[email protected]&a1=195432656332&a2=Europe&a3=Barcelone-Spain

I use first_name and last_name and email the way it says to do it in the Calendly documentation to prefill from the URL.

How can we fix this?

Sorry I had wrote this same question in a previous topic but decided to create a new topic since the original was already resolved.
