Layer opacity issue

So I’m fairly new to Toon Boom Harmony and switching over from Anime Studio Pro. I’m playing with setting up a cut out character’s body parts on separate layers. However they are looking as if they have a transparency on them until I select them. Probably a dumb question, but how can I have all the layers without that transparency?

maybe you enable the light table feature.
so, you press Shift+L to disable light table.

click lower left quarter from Camera view, the light Icon to disable light table.
