Respond to PowerApp action returns inconsistent boolean value

I have a flow that initializes a boolean "success" variable as false, does work, then sets the variable to true and returns that value as a yes/no response to PowerApps action. I have other flows that do this and they return true as expected. However, this flow returns True and my PowerApp doesn't like it.

In the PowerApp I initialize the variable as a false boolean. Then I have a button that runs the flow and stores the response. After it runs successfully I go to check the variables and it doesn't even say it's set to true. It says No Value like it wasn't able to process True with the capital T.

pseudo code:

PowerApp -

AppStart

Set(Step2Success, false)

2nd Screen

Set(WorkflowRunning, true);
Set(Step2Success, WorkflowName.Run(item.ID).status);
Set(WorkflowRunning, false);

PowerAutomate -

Initialize Variable action - success as Boolean = false

Scope All Workflow Work

last action in this scope is Set Variable action - success = true

Respond to a PowerApp or flow action - Yes/No output "Status" = variables('success')

Checking the run history the flow shows True is returned. And Step2Success says No Value in variables tab of PowerApps.

As I mentioned, I took this approach with other flows and looking at the output of the respond action it is lowercase true returned and the PowerApp variable is updated properly (Step1Success is actually this way).
