'Add to cart' does not disappear when there is no price

[phildrink]

Hello,
I have a problem with the Virtuemart shop on priceless products (VM3).
The button 'Add to cart' does not disappear when there is no price...

I want to remove this 'Add to cart' button, which is still present on the product pages WITHOUT PRICE.

I do not know where it comes from.
Would anyone have an idea?

Regards.

You don't say exactly which version of "VM3" but I just tested with the current versions, Joomla 3.7.5 VirtueMart 3.2.4 using the default templates, and with blank product price fields neither the add to cart button nor the price fields are displayed, just the call for price button.
