Valid Number of Uses Not Working

I am using the Pro version.

It says in the documentation that if you want to give the customer unlimited usage then enter "0" or leave the field blank. When I enter zero or leave the field blank I get the message below.

"Please enter a valid number of uses"

Yes, you are right, entering 0 does not work, I will update the documentation. To get the coupon to be unlimited, you need to leave both the textfield and the dropdown in number of uses blank.

Got it. Thanks!!
