Hi @Suggy 

As the article mentioned, this behavior is due to the asynchronous nature of scripts. The form gets submitted before the response from the GlideAjax call returns.

You can refer to the screenshot below for a detailed explanation, along with a couple of posts where I provided accepted solutions for different use cases.

Ref: 
Onsubmit catalog client script is not aborting the form from submitting.

Validate group names in a list collector variable to check if selected group has less than 2 members

I see that the best and easy solution is to use "EfficientGlideRecord" 🙂
