It appears that this issue has been addressed here.
Have you had the opportunity to address the trouble shooting that has been suggested in the previous thread?
To troubleshoot, you will want to power down your panel fully, transformer first then internal battery. Then remove the cell sled from the panel and wait about five minutes and re-seat the module. You’ll feel a light click to know its all the way seated. Then plug in the battery, followed by the transformer. Wait a few minutes and check signalling, any change?
Once powered up, be sure to check signalling. Additionally, what is the Firmware build version? This can be confirmed via the panel System Info and Usage -> System Info
