ftui tries to get chart-data from wrong file

[Lutzion]

today, on the 01.02.2023 i try to see the chart-data of the last days.

So i click the navigator to move date to 27.01.2023, but i dont get any data.
With fhem global.verbose = 5 i get the log entries:

2023.02.01 21:39:16 4: WEB_192.168.64.2_55640 GET /fhem/?cmd=get+FileLog_Bewegung_MDIR_O_4F96CF+-+-+**2023-01-27**_00%3A00%3A00+**2023-01-28**_00%3A00%3A00+4%3Atrigger_cnt&asyncCmd=0&fwcsrf=csrf_355115176078942&XHR=1; BUFLEN:0

2023.02.01 21:39:16 4: FileLog_Bewegung_MDIR_O_4F96CF get: **Input file** ./log/Bewegung_MDIR_O_4F96CF-**2023-02**.log, from:**2023-01-27**_00:00:00  to:**2023-01-28**_00:00:00
2023.02.01 21:39:16 4: FileLog_Bewegung_MDIR_O_4F96CF get: line 1, regexp:trigger_cnt, col:3, output lines:0

The problem seems to be
get: Input file ./log/Bewegung_MDIR_O_4F96CF-2023-02.log, from:2023-01-27_00:00:00 to:2023-01-28_00:00:00

ftui tries to read the chart-data from 2023-01-27 to 2023-01-28 from the file *2023-02.log.
That means ftui chooses the wrong logfile.
