My Custom Styling Changes Saved and Applied But the Form Does Not Reflect Change

I am using Contact 7 Style to further customize the style of the Monochrome Light template form, including changing font, width of form, button color etc. I made sure “Contact Form 1” was selected in the Edit screen. I’ve made needed style changes.

The “Preview Area” image on left shows my changes and is correct. However, the preview image in right sidebar does not show the changes. It still shows the default Monochrome Light form without my custom changes.

I have clicked “Update Style” button at bottom, then clicked the blue Update wordpress button also, then clicked the “Go to CF7” button and copied the shortcode for Contact Form 1 that I’m editing, pasted in to my page, saved everything – but the form showing on my Contact page is the original default Contact 7 form. It is not the Monochrome Light template styling, nor does it have the additional custom styling I added in the Style tool. Any idea what I’m missing?

I’m building locally, using Flywheel, but here is the Flywheel live link (to my Contact page where I’m using form), hopefully it works for you. It times out after some time.
