Describe the bug
Currently the Calculate button shows up at the last question, but this does not show up when a question is skipped.
To Reproduce
On legal entity question, if the user clicks on Sole Proprietorship or Partnership, the form will skip the Salary question. But upon reaching the end of the questions, the Calculate button does not show up.
On legal entity question, if the user clicks on S Corporation or LLC, the form will continue onto the Salary question. Then the Calculate button will show up.
Expected behavior
Regardless of the path that the user takes, the Calculate button should show up on the last question. In this case, that last question is the Income question. Wonder if we can just set it so that everytime the progress bar reaches 100%, the Calculate button shows up
Screenshots
This is what's expected:

When the question on Salary is skipped, this is what I see
