Can't uncheck slide layers
I am very new to Storyline and I am running into an issue when building in slide layers. I am able to create the new layer, add a trigger to bring it up, and add my content. My issue is that I can't uncheck the new layer from the bottom left panel to get back to working on my base layer. I feel like I must be doing something silly wrong, but I can't for the life of me find an answer. Is it something wrong with my computer or I am missing something?
Thanks for any help!
