Hello, I'm having a problem with the Vision "alarm status table" component. With ACK mode set to manual, sometimes have this problem after rebooting my PC. Active but unacknowledged alarms cannot be acknowledged; the ACK button remains disabled. I noticed in the designer where the component is called that if I select alarms, the selected alarm dataset remains in or with 0 row . I'm attaching some images to better explain my problem. Thank you ![img_1](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/f/cf85f97cf44d21eb63ad849c8e15d08755a37883.jpeg) ![img_2](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/e/ce813866347a1563490009ad2c5a405b9e2cae0c.jpeg) ![img_3](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/1/91266e7b1a405a30ffacc55d1d3701bc44c6e5c8.jpeg) ---

Add more information Ignition version 8.1.49 Vision I noticed that, when I select alarms with the checkbox in “alarm status table”, this error appears in the console output in the designer. ```python
