Works on some forms but not all

Seems to work on some of my simple CF7 forms but not on some others that are more complicated with conditional logic. If you look at the source code and hover over the code after the submit button, the browser highlights a field where the spinner should be. (I know this b/c this is where it is on the forms that work). This is initially good b/c spinners aren’t supposed to show until after you click submit. But for some reason, it doesn’t show itself when you click submit even though I know it’s there just waiting to show itself.
