Describe the problem/error/question

Hello n8n developers, when I was using the “chat memory manager”, I found that the information was not recorded completely.
I only set up two chat memory manager modules, the first one to record user input, and the second one to read it.
However, when I input in the order of 1, 2, 3, 4, 5, 6, 7, I found that the memory module did not correctly record the information.

What is the error message (if any)?

The pattern seems to be: the first time it records normally, the second time it overwrites the first record; the third time it extends the record normally (at this point there are two records), the fourth time it overwrites the third record.
