Three similar issues: 1. Changing Icons on Tab interactions inhibits "Visited" state and 2. Visited Buttons on Lessons Overview Slide, undo on the last button visit and 3. Creating a Shape Button with Image, can't click anywhere on Button for interaction

Hi there, I am having three issues with my Storyline 360 course and would love some input:

1. On one of the integrated tab interactions, if I leave everything alone and set-up a variable to show the next button only after all of the tabs are visited, it works fine. But when I want to customize the icons on the tabs, I can't get the "visited" state to be recognized anymore. How do I fix that?

2. I have several "inserted-shape" buttons on my Lessons page. After a learner clicks the button and finishes the Lesson, it returns them to this slide to take the next lesson, showing the previous button in a different color showing it is visited. This works fine until I get to the last lesson. When the learner returns to the Lesson page for that last lesson, all of the previous lessons are now showing up as grey = not visited. I don't see anything glaringly wrong. Any ideas?

3. I create a button on a slide that is a rectangle shape with an image in the center and a word on the top (three separate items). I want the user to be able to click on any part of that button to get to the corresponding slide, but it only allows the user to click one tiny area to work. I have them "grouped" but it doesn't seem to recognize them as one button. Ideas?

Thank you!! :-)
