Ninja Forms DB migration fatal error

Hi, I’m using Ninja Forms 3.13.1 without any add-ons.

A NF migration function runs everyday which ends on a fatal error. It’s trying to query a table called “IF”, a SQL keyword.

PHP Fatal error:  Uncaught TypeError: mysqli_num_fields(): Argument #1 ($result) must be of type mysqli_result, false given in /home/eastside/public_html/wp-includes/class-wpdb.php:3863
