It looks to me like the problem is your theme. If you look at this screenshot, there are <code> tags in the markup where the progress bar should be rendered.

These are not added by the Progress Bar plugin. It’s possible (probable) that those tags are being added by the theme which is processing the content and running it through a filter which is interpreting the progress bar markup differently than it was intended and resulting in the bar not displaying. You can try switching to a different theme to see if it goes away which will tell you if the theme is the culprit. It’s also possible those tags are being added by WooCommerce, but I would check the theme first.
If it’s a result of the theme, it’s possible there’s another shortcode you can wrap around the progress bar shortcode that disables this auto-formatting of the progress bar’s shortcode markup. You would need to contact the theme developer for support.
