Color palette disappearing issue

Hi there,

I am working in Harmony Premium 20 and while working in scenes the color palette has been disappearing completely and I am unable to create any new colors at all. I am not sure what I am doing but it seems like it is happening the more complex the scene and how many version I have. The color palette is completely blank now and I don’t know what to do other than start a brand new scene. I’ve posted a screenshot of what I’m seeing. Thank you in advance for any help on this matter.
