Hey guys, does anyone know how adding the Vibe Chains in the level editor works?

I published a chart that has four sections where you can fill up the vibe meter (the yellow powerup meter), but while playing the custom level myself I discovered that they don't actually fill the meter?

The first section is the only section of the chart that actually works, and even then it rewards the player BEFORE the combo actually finishes, the rest just don't work despite the enemies showing that they give the player the powerup.

I currently have the chains overlayed on top of the enemy sprites in a single line down the middle of the section, starting just before the first entity to ensure every entity is affected. Before, I only overlayed them on top of the sprites directly and then I tried filling out the full row for the entire section.

Is having a bunch of them at once causing the problem? Or does the icon need to be below the entity? I'm completely stumped at this point and any insight would be appreciated.
