BC660K_GL does not enter to deepsleep mode inmediatly after entering in PSM mode

Hi, I have been working on an application with the BC660K_GL module, the idea is to optimize the power usage, so for that I have the following configuration:
Send UDP message with RAI flag = 1, slplocktimes = 0, eDRX desactivated, TAU = “01000011” and active timer = “00000000”.
with this configuration, after sending the message, the module goes into deep sleep mode almost immediately but in one of the modules this does not happen.


Looking at the image above, you can see in two of them (green rectangle) that the module enters deepsleep at the same time they enter PSM, but the third one was almost 7 seconds in idle mode before entering deepsleep mode. I attach also the logs

(left side: expected result, right side: module with the problem)
What could be causing the problem?
