The buttons on the feedback master

I'm guessing that whomever prepped the file deleted the button placeholder from the Feedback Master Layout because each type of Question slide in scene 5 has its own color. My other guess is that they assumed anyone using the template would duplicate one of those existing slides or import one into another file, as needed. In other words, they didn't expect that the button placeholder would be needed. 

Unfortunately, if you insert a new Question slide, Storyline will add a default Continue button to the Incorrect and Correct layers (as you've seen).

Here are some possible paths forward:

• Only duplicate and/or import the existing Question slides from scene 5. 
• Add new button placeholders to the Feedback Master layouts that have the basic size & placement you want. (You can change colors later on a given slide.)
