Price Plan Element – with $0 pricing display issue

Hello. I’m using your “Price Plan” element in visual composer. For items with prices above 0, it displays correctly. However, I want one of the price table options to have a price of $0. When I enter 0 into the “Price Value” field, the pricing table displays simple “$” instead of “$0”. See the screenshots attached for images of the element settings, and the rendered element on the page. I’m guessing this is an issue with the logic in the code checking for a value in that field, and the 0 returning false. How can this be fixed? Thank you!
