Layer not animating in Preview or Render - other layers do

[Avem]

I did an animation with two layers, one for the colours and one for the lines.

Upon exporting it once, both layers would animate, but I wanted to re-export it under a different format (.gif)

After doing so, I noticed the lines layer no longer animated in the export, and the preview didn't show it animating either. I checked the schematic, and everything is hooked up. 

I tried cloning and deleting the lines layer, but nothing changed, I also tested other layers by putting a frame counter on a new layer and it animated. The only thing not animating is the lines layer. All of the drawings still exist and are visible in the workplace.

How do I get the lines layer to be used in the output again?

I think if you could share some screenshots. It seems like you've turned something off. A screenshot including your timeline (and tell us which is the missing column) and another showing both schematics.

Oop, yeah sorry! shouldve included it in the first message

The one not animating is the layer that's unlocked

Unfortunately I can't see anything wrong here. But you did say that it rendered properly, so it would seem like it's an issue with the gif rendering.

However, I would ask, do you really need to have the lines and fill on a different column? It can make putting an animation together more tricky as you have 2 columns to retime. Putting your fills in the same level keeps things simple and easier to manage.
