[your-subject] and [your-name] showing

Hello,

Today I saw that all messages are showing [your-subject] and [your-name] <[your-email]> in Flamingo. I read your doc here: https://contactform7.com/save-submitted-messages-with-flamingo/ and fixed that for the future contact form submissions.

My question is: can we fix that for messages submitted before we added these lines of code?

Thanks in advance for your help.

Best regards,
Fiona.
