[Plugin: Pricing Deals for WooCommerce] Warning in vtprd-apply-rules.php

I have installed WooCommerce with Pricing Deals on our website and under the products, I’m getting these two warnings:
Warning: Invalid argument supplied for foreach() in /home/vintage/public_html/wp-content/plugins/pricing-deals-for-woocommerce/core/vtprd-apply-rules.php on line 2178
Warning: array_values() expects parameter 1 to be array, boolean given in /home/vintage/public_html/wp-content/plugins/pricing-deals-for-woocommerce/core/vtprd-apply-rules.php on line 2185

I haven’t been able to find a solution, but I found this post in wordpress plugins support, which suggests you are aware of the bug
http://wordpress.org/support/topic/warnings-thrown-in-vtprd-apply-rulesphp-on-line-12

By “googling” the warning, I found out that many other websites get the same warning with Pricing Deals plugin
Google this “vtprd-apply-rules.php on line” and you will see what I mean.

Help please, thank you
