Hi @mz3bel
It might be that the Select activity does not fully support your select dropdown menu.
Just to be sure, please make sure your Studio is updated to the latest version 2019.4.0 and that all your packages in the Package Manager are also up to date.
If it turns out that it still doesn’t work, please see the list of topics here:

They all have a post marked as solution on how to select a dropdown menu element.
