5500AC2 Weird Issue with DALI Lights & Scheduling

I'm currently stuck with an odd issue where i've got 2 x group address that randomly turn off at random times of an afternoon that occurs every day.
One group address is DALI controlled lighting and the other is a relay channel.

For some reason in the 5500AC2 logs, it shows each group suddenly ramps down to OFF over 12 seconds. Which I have no programming whatsoever for ramping down the lights. All the DALI lights on the group address are purely controlled via a Schedule to turn on and off within the 5500AC2 and the DALI gateway.
No other input devices control these DALI lights.

Also what is very strange is that the logs show that 'Sporties Sign (46)' group address, ramps down over 12s. Whereas its on a 16 channel Spacelogic relay? So in theory It cannot ramp down.

I've attached a log file from the Application Controller showing the logs for the particular group address: 'Outdoor GM Row-1'(47) all times of the issue occurring have been highlighted.

Any help would be greatly appreciated.
