On month roll bmw.*.chargingSessions.YYYY-MM gets previous months sessions as well

[j64bit]

Describe the bug
In a new month the next directory in bmw.0.[VIN].chargingSessions.YYYY-MM gets created.
Unfortunately it then also contain the previous months data, which was copied over (so from MM-1).

Next steps then are all fine: New charging sessions get added correctly. The totals are correctly including the MM month, only.

To Reproduce
Wait for a new month with charging sessions in current month

Expected behavior
to not double/copy over the MM-1 data

Screenshots & Logfiles
none
