Hello, I am running into the same issue LumpySimon had in his topic here (please scroll to the later posts).
This was two years ago, and the topic ended with the a statement that the issue will fixed in the next version update. I am currently running into this same bug/issue and would like to know if there is a way to presently resolve it?
To summarize the issue/bug:
I have implemented a Pricing Field - Option drop down with set donation amounts. The last select option is '1,000+', priced at $0. When selected, it triggers the conditional requirements for a Product - User defined field to display. The user can then input in their custom donation amount.
However, once on the PayPal checkout page, it display two products. Under the purpose label it states: '1,000+' and 'Custom Donation Amount'.
I would like to remove the '1,000+' product/purpose from being displayed.
Thank you in advance.
