Hi @dearjudy,
In reality you are using a very outdated version of the plugin, and my recommendation is to upgrade to the newest version, because this behavior was corrected some time ago.
To get the latest version of the plugin you simply should visit the download link received after purchase the plugin, or you can generate it again through the contact page of my website:

However, if you prefer a rapid and effective solution with your current version of the plugin:
1. Assign to each date field a custom class name, for example: my-date
Note: If the field has assigned a class name you simply should separate them by a space character.
2. Insert an “Instruct. Text” field in the form, and enter as the attribute: “Instructions for users”, the piece of code below:
<script>
fbuilderjQuery(document).one('showHideDepEvent', function(){
fbuilderjQuery('.my-date input').val('');
});</script>
and that’s all.
If you need more help with the professional version of the plugin you should contact me through my private support page:
