[Plugin: Contact Form 7 to Database Extension] _wpcf7_version column added to database after adding

Was using Contact Form 7 and the Contact Form to DB Extension fine for a few weeks.

Given my need I purchased the Contact Form to DB Extension Edit plugin and added it to my site. All other plugins were up-to-date.

I had some trouble when I first tried editing column data; some rows would work fine, but the top row in one table would not give me the content when I clicked to edit, just an empty cell editor, for any column in that row.

To test if it was a 1st row or data issue, I added some additional data via a form submission.

When I went back to the database view, extra columns were inserted in my data table; columns names: _wpcf7 _wpcf7_version -vpcf7_unit_tag _wponce _wpcf7_is_ajax_call

Using Google Chrome as the browser.

What went wrong?

How can I get back to the normal form/data – and stop the new columns from being injected? (afraid to try an update to another form/database pair as that data is “production” quality, but other site users may do so soon…)
