Hi Steve, thanks for reaching out.
Your first issue has been, identified, fixed, and released in the latest version of Woo Schedule.
The second issue is a result of labeling. The inputs were labeled AM and PM. However, you are not prevented from inputting PM times in either input box. The box to the left simply needs to be earlier than the box on the right. In short, we have taken this as a suggestion and have renamed both labels to AM/PM.
Please download the latest version of the woocommerce scheduling plugin from your “my accounts” page. Let us know if you continue to experience issues.
