Random white box/background appearing on image
Hi everyone,
I'm pretty new to Adobe animate, but have been using Photoshop for quite some time. I've been trying to animate this retro loading bar in Adobe animate (probably not the most efficient way, but it was working alright) when I got to the last couple of "blocks" of the loading bar, I started having a white background appear on the shape. The same image I have used for all the other layers, which have no problems.
The strange thing is, the white background only moves up to a certain point, almost like there is a layer mask or something going on. I've tried undo-ing but that didn't seem to fix anything.

I'm pretty stumped on what the issue is, its probably something super simple, but I'm very unsure as to what it could be. Any help is greatly appreciated!
