At this time there is no way to edit or delete your withdrawal method. But you can easily create a new withdrawal method by selecting + Create new underneath the withdrawal method drop-down. 

The most recently created or used withdrawal method will always appear at the top of the drop-down menu.

Be aware, you can only have one PayPal account linked to your Spinnup account and this PayPal account cannot be associated with any other Spinnup accounts.

Please also ensure that you enter the correct PayPal email when creating a withdrawal method. If you have created a withdrawal method with the wrong PayPal email, please contact support.
