Vision Client Troubleshooting

I am troubleshooting a vision client. One of my components has the pic below in the upper left corner of the component. Where can I find documentation to tell me what this means? The component looks fine in the designer. Thank you for your help.

This image should suffice. From this page in the docs.

That’s exactly what I needed. I guess I just didn’t put the correct wording into the search in the manual. Thanks
