PHP Coder required for Wordpress Woocommerce data import issue

We have a 2 websites that run on a Wordpress Multisite Woocommerce system. Both websites have a function to import a CSV file to update a listing of stockists.
e.g https://www.vets-choice.co.uk/find-a-stockist/
On one website, the import routine works correctly and updates the stockists, however on the other website the import is not correct.
The json data that is imported and added to the db is not in the format that the locater tool needs for Vets Choice.
an import produces this
{"id":5,"title":"Sainsbury's","lat":,"lng":,"name":"","address":"","phone":"","web":"","url":"","text":""}
but it needs to be this
{"id":1,"title":"Saltburn Vets","address1":Windsor Road,"address2":Salt-burn-by-the-sea,"city":"Cleveland","state":"North Yorkshire","postcode":"TS12 1AZ","phone":" 01287 625050","url":"https://www.saltburnvets.com/","lng":"54.581256","lat":"-0.97883"}

We require ongoing support for this website, so in this instance we are looking for a fixed & final price to resolve this issue.

All code is held in a Github repo and access will be granted to the repo.
An admin login will be provided for Wordpress
A staging website is available for testing and any deployments to the Develop branch will automatically be uploaded to the staging website.
No direct access will be given to the server, including FTP, SSH, Plesk etc to avoid the repo becoming out of sync.
If you have any questions, we'd kindly request that you post them on the job board here rather than contacting us directly.

We have ongoing work and multiple projects that we require PHP/developer support with, so we are looking to form a long term partnership with a provider who can communicate well, is prompt in responses and will conduct their work in a timely manner.

We run on Zoho and will add you to a Zoho Cliq channel so that you can communicate directly with us. We may also add you to our Zoho Projects tool and require you to update tasks within that tool (however this is not likely in this single case)
Please do not submit any proposals in the first 10 minutes, we'll assume these are all generic/template responses and will be rejected.
