Contact Form Bug – Migrated WordPress

I think i have found a bug. Thou im guessing its self inflicted.
I thought I explain what I think is happening first.
The issue is with the Enfold contact form.

A new install of WordPress no issues, edit the contact form on the page and save the changed values.
If I edit this page again the saved values show. No issues here.

The problem comes in to play I have noticed is when you migrate the website to another domain.
Our process is we move the wp-content folder to a new install of WordPress, migrate the database across and change all sql fields from previous domain to new domain with a script we have.
We have done this with thousands of website and no issues at all.
The site works fine and as far as i can work out all other ‘modules’ work as expected expect the contact form.

What I discovered is the following:
– edit a page with a contact form
– contact from is set back to default values
– edit values to new values
– save page
– Test the published page
So far testing the page displays correct values
now is the confusing bit
– edit the same page
– edit the contact form
– default values back not the saved

Even noticed if i edit the page without touching the contact form and save the page , default values will be saved.

Im assuming there is a line somewhere for recall that might be pointing at the old database?
Or if its confused it will recall default values?

Any incite to how the contact form saves it values and recalls them might help.

Thanks
