View Filter Nodes not Assigning Value

Hello all, I have been learning Dynamo for a few months now and recently started on a workflow to create a 3D view showing all elements that use a specific level as a reference. I started with a skeleton workflow just to get it working but I can’t get the view filter nodes to work how I want. They create the filter but don’t assign a value. I have attached a snippet of the code blocks I am using; I am using Data shapes UI to get the category and level I want to filter. I know these nodes handle text parameters better but I want to keep the workflow as parametric as possible so I would like to stick with using dropdown parameters as opposed to creating a new text based parameter. Any help getting these nodes to make the desired filter would be greatly appreciated, thank you.

I am a first-time poster so I couldn’t include these snippets in the original post, but this is the filter the nodes are creating.

And this is what I would like for them to create.
