List of tabs does not refresh

While configuring the button component, I find that if I select the ‘Go To Tab’ Action (on right hand side), the list of tabs that are available is not current. Newly added tabs do not show. How can I refresh this list so that the information is current? It does not help to click the refresh button next to the source file (google sheets). If I recreate App using the same data, the tab list refreshes. I don’t wish to recreate app each time this happens. Please help.

Does refreshing the builder work?

Do you have actual tabs showing in your tab list at the top left of the builder, or are you referring to new sheet tabs that haven’t had an app tab created yet?
