Hi @Bob_Chambers and welcome to the Forum!
Sincere apologies for the delay in responding here! Can you please confirm you are still experiencing this issue?
If yes, would you mind recording a screencast to help us visualize the behaviour you are getting? Loom is a great app for video screencasts: https://www.useloom.com/
In your video screencast, we recommend that you use a Chrome Incognito window and have your Javascript console open:
Try to include the entire browser window, including URL bar, in the video screencast.
If you don’t feel comfortable sharing the Screencast publicly in the this thread, feel free to DM me (You just need to click on my name above and select “Message”).
Thank you Bob! Looking forward to your reply!
