waitress on top right does not dissapear after waitress$close()

[pachadotdev]

I followed https://waiter.john-coene.com/#/waitress#notifications to have waitress_1, waitress_2, etc. When the progress bar finishes, the elements for the corresponding tab are ok, but the progress bar does not disappear on close.

Here's what I'm doing pachadotdev/tradestatistics-visualization-with-shiny@2d2f1cc

Please tell me how I can help to fix this.

Do you have a reproducible example? I can't run your repo and the example in the documentation works just fine.
