Creating a conditional field is deleting previous entries.

Hi,

Creating a conditional field is deleting previous entries. To reproduce follow below steps –

– Create a simple form with 1 or 2 fields like text or number
– Create one entry for the form
– Now create a conditional field .. like one field will say “is it a project?” with drop down “yes” and “no”. If user choose “yes”, it will show a text field to enter project id.
– Save the form. The previous form entry will vanish.. I checked the database as well.

This is scary. How it is deleting an entry from the database altogether. Which is triggering the deletion? I am very scared to do anything with my forms now, not sure what else will do the same. And once deleted, there is no option to import entries.

I have few questions
– What is the best way to secure form entries? I don’t want any deletion in any way
– Is there any way to import entries once exported in csv?
– Can I prevent any deletion from the database even explicitly or  programmatically. Is it possible through wordpress role?
– I am using all forms in my custom program heavily. If I need to migrate to Ninja form eventually, which I don’t want to :), do I need to change all my codes manually?

Need your wise advice urgently…
