Hello and thank you for contacting the Toolset support forum.
To better assist you with this issue, I'll need to take a closer look at the view or content template where this happens. Your next reply will be private to let you share credentials safely. Please take a database backup before sharing credentials.
If you cannot share credentials to your website, I'll create a new test site for you so you can reproduce the same issue on it, and I'll help find a solution for it.
Thank you for the credentials. The issue comes from the fact that the field values are not valid URLs. They do not contain the leading https:// or http://
I edited the post and added https:// to facebook URL and it fixed the issue.
If you want to enforce the validation of URL fields, you can activate it on the custom field definition.
I hope this helps. Let me know if you have further questions.
