Can you illustrate or post an image of what the bar with the spark looks like?

Sure, Here is a Picture of The Loading Bar about Halfway, and The Spark Animation Where it Should Be When The Bar is Halfway

If the spark footage has an alpha channel, as is likely, then make sure, it is activated - right-click on the event, launch Properties, and check that Alpha Channel in the Media tab is set to Straight.

Now, animate the Spark's position in its Pan-Crop window to track the leading edge of the bar.
