Only background layer is visible


I’m a fellow user to Aseprite. I actually haven’t opened up any of my projects in a little over a year. I’m not sure if this has anything to do with my issue, but I can’t seem to find any of my other layers within the project. I’m only able to see a "background’’ layer but I remember at least working with about 8 or 10. I’d like to continue working on those projects, but I’m not sure if I ran into a dead end and need to start over or if there is a way to fix this issue. Any help would be greatly appreciated.

Edited: Here is a gif of the issue in Aseprite. Notice that the background layer is the only visible layer. The last time I worked on this project there were at least 5 layers. The buildings, lights, fog, the bridge, the background buildings, etc. Why am I only able to see the background layer? I do not remember merging any layers together after working on this project.
