Weblist select not working as expected

I have a select list where I can select a scenario and and soon as I select the scenario in the list then the scenario page loads.

The automation is selects / clicks on the list item then the item is selected but the page does not load.

when I manually perform the step to select the scenario from the list then the scenario page loads

the automation does the same thing but the page does not load.

how would I get around this? scenario’s are a core part of the application and I currently cannot select & load them via the automation. I’ve tried Click, Click using Java script - I just cannot find a command that works there.

I will be very grateful for any assistance
