Hey ,
I was not able to reproduce the issue. After completing all of the steps, I concluded in Test1 (1 instance of of WBP_Test exist) and in Test2 (No instance of WBP_Test exist). I completed this in 4.17.1. If there is anyway for you to attach a few images of your setup showing the issue that’d be great. Let me know if there is anything else that I can help you with.
Sincerely,
