woocommerce_get_price_html filter not working

Hello,

I need help with your plugin. I am using the woocommerce filter woocommerce_get_price_html to add description to the price.

What it is suppose to do is to add different price description after the price based on product category and if is it variable product. The filter works fine everywhere on the website. When I turn the plugin off, than I get correct results as well with the default WordPress variation select.

Can you please help me to make this work with your plugin?

Thanks,

Josef
