High consumption of BC660k after PSM

IoT Modules LPWA Module
1

I have been making different measurements of system consumption by logging into PSM and sending messages. I have found that at approximately 4 hours and 30 minutes when a message is sent, the module is active for 5 minutes before going back to PSM.

First case: entering and exiting PSM to send messages. The system enters and exits PSM to send data without any problem, the consumption graph is always the same. When the execution approaches 4 hours and a half, when sending data, the module remains active for more than 5 minutes until it enters PSM. (upper image)

Second case: PSM at 4:30 and sending data at 5 hours. I left the system in PSM for 4:30, it woke up and re-entered PSM. After 30 minutes, the process of sending data is carried out and it is when the excessive consumption appears, leaving the module awake until it enters PSM after 5 minutes. (lower image)

Can you help me by indicating what may be the cause of this behaviour?
Thank you

Please provide the detailed firmware version of BC660K. This issue needs to be analyzed through the EPAT Log

The firmware is:
Quectel_BC660K-GL
Revision: BC660KGLAAR01A05_01.200.01.200

I used the EPAT tool to get the logs from the device. I attach the second case Log file from EPAT.
Can you help me to understand the logs? I have tried to compare the behaviour of the module in the state that remains active after sending with the logs that the module generates in the case that once the message has been sent it enters PSM.
