In the blueprint editor when selecting multiple components and resetting a property that exists on both components to its default value, when the components had different default values the editor runs into an ensure and both components' properties are reset to one of the default values which is incorrect for the others.
For example: create a parent blueprint with two StaticMeshComponents with different values for TickInterval. Create a child blueprint that overrides TickInterval for both components. Now select both components in the Blueprint Editor and attempt to reset the property. The reset doesn't work as intended since both components receive the same value.
