Flow Button Bar - Buttons - User is not being presented with choices

[joemajor23]

We have two different sandboxes with different package versions:

Dev Sandbox:

• FlowScreenComponentsBasePack - 3.0.18
• FlowActionsBasePack - 2.32

UAT Sandbox:

• FlowScreenComponentsBasePack - 3.3.1
• FlowActionsBasePack - 3.15

When running a screen flow with a screen with a flow button bar in the Dev sandbox the component is correctly displayed and the user is presented with a choice of 3 buttons.
Flow debug. Note debug termination before screen with flow button bar is displayed.

Screen is visible for button selection.

In the UAT sandbox the screen with the flow button bar is not displayed and it appears a value is being defaulted:

The xml for the flow appears to contain a default value for Queue in both sandboxes, which is the value being applied.

The default value does not appear to be something that can be changed and is not a UI configurable setting. I am thinking that perhaps this value was added when generated in an older version but not considered but now is?
