Odd calls from this month listed under last month's call log

[Erft]

I noticed something very bizarre when I looked at this month's and last month's call log. Today is November 22 2020. My call log goes to November 22 2020. Then you scroll down to October 2020. Underneath October 1, it starts up with November again, and the November calls listed are not listed in the proper November area at the top of the call log. The call log says these are calls from November 2nd to the 18th. When I look at the top of the log, where the 2nd to the 22nd of November are, none of the calls are in there.

At first I thought that perhaps these were calls that I didn't pick up, although those aren't usually listed in the call log. Then I saw that normal call clearing was in there too.
It's not 1800 numbers.

What's going on?

I’m seeing this as well. I don’t know why the call dates aren’t sorted properly, and I don’t know why 0:00 duration calls are listed.
However, I hope the 0:00 duration calls are maintained in the call logs from now on.

Looking at my own call logs (not FPL’s), I do have outgoing calls that I disconnected before the other side answered. They are shown as normal call clearing in FPL’s call logs with 0:00 duration.
