Daikin Automation - Unit turns off automatically

I have integrated my Daikin AC units (5 ACs - Local APIs) and I have 5 Climates in my dashboard.
Everything works great for all of them except 1.

I have an automation to turn Master AC on at 19:30 and another one to turn it off at 6:45.
The AC turns on at 19:30 but it somehow turns itself off around 20:06 everyday.
I then switch it on from the IR controller and stays on all night to turn off at 6:45.

Exact same automation works for other 2 rooms without any problem.
I have checked and the entity is not part of any other automation.
The history says “Turned off” which means it is not an automation or another HA user.
It is not turned off by the remote or the native app itself.
I don’t know what else to check!!!

Any ideas?

The history:
Turned off
20:06:59 - 1 hour ago
Changed to Cool triggered by automation AC Master ON triggered by time
19:30:00 - 2 hours ago

The automation:
