Model Builder: Tool forgets / looses settings

[GeoFUNKE]

Hi,

I have a model, that adds locations and routes to a Last MIle Delivery Layer and solves it.

When adjusting the settings in the "Add Locations" that add the routes, I want to use a field from the input data as the route name and set the "Append to existing Locations" to FALSE.
The tool lets me select the field from the dropdown and remove the checkmark from the checkbox. Unfortunately when closing the tool it instantly forgets / losoes those settings and just leaves teh Name field empty while having the chackpox for Append to existing locations checked.

Is this a known bug, is there any workaround to solve this?

Best

@Hi @GeoFUNKE,
I am sorry you are experiencing this odd behavior. Please could you share a snapshot of the model and the tool dialog which shows the issue mentioned above? Alternatively you could share a toolbox with the model as well. This will help us replicate the issue. Pls also share the ArcGIS Pro version that you see this issue. 

Thank you!
