Issue with layer dissapearing from symbol in test (pls help T-T)

Hi, I am doing a project for a company where they want me to make interactive assets on their website. It's about bugs so there are little bugs that move when you hover over them, coding that has been easy however I have one really weird issue going on. One of my symbols loses an entire layer when it exports, the layer plays normally in the program, and the legs show up outside of the symbol, but not when I test it within the symbol, everything else works fine. Below is a photo of the messed up export and my layers and setup in the app.

I also have another animated symbol that works perfectly fine and both are set up the same and are on the same file.

Is this the test just being weird if I give this to the coders will they just have a bug with no legs? Is there some super random user error I am making? Any help or suggestions is greatly appreciated.
