BLF Hint not working properly - wrong INSERT statement?

Hello,

i am using FreePBX Version 15.0.16.38 and i think i found a little bug:

When entering a TimeGroup with a single Day (e.g. Thursday only) with a special time (13-14 o'clock) it gets inserted like this into the asterisk database:

MariaDB [asterisk]> select * from timegroups_details;

40 |           2 | 13:00-14:00|thu||

 
When i check the condition with

/var/lib/asterisk/bin/schedtc.php --debug

i will get the following output:

[admin@pbxod ~]# /var/lib/asterisk/bin/schedtc.php --debug
Time Now:13:28|Thu|16|Jan|Europe/Berlin

==Working with TimeCondition:lunch==
INVERTED BLF: true (NOT_INUSE = INUSE & INUSE = NOT_INUSE)
OVERRIDE MODE: not set
=>13:00-14:00|thu|*|*|Europe/Berlin is not now
TIME MATCHED: False (NOT_INUSE)
BLF MODE: False (NOT_INUSE)
Privilege: Command
Changing TC2 to NOT_INUSE

Allthough timezone and settings are correct:

[admin@pbxod ~]# date
Thu Jan 16 13:28:56 CET 2020
[admin@pbxod ~]# ls -l /etc/localtime
lrwxrwxrwx 1 root root 33 Jan 13 09:11 /etc/localtime -> /usr/share/zoneinfo/Europe/Berlin

When i update the Database Entry to the follwing:

MariaDB [asterisk]> select * from timegroups_details;
40 | 2 | 13:00-14:00|thu-thu||

i get

[admin@pbxod ~]# /var/lib/asterisk/bin/schedtc.php --debug
Time Now:13:33|Thu|16|Jan|Europe/Berlin


==Working with TimeCondition:lunch==
INVERTED BLF: true (NOT_INUSE = INUSE & INUSE = NOT_INUSE)
OVERRIDE MODE: not set
=>13:00-14:00|thu|*|*|Europe/Berlin is now
TIME MATCHED: True (INUSE)
BLF MODE: True (INUSE)
Privilege: Command
Changing TC2 to INUSE

Now the BLF Mode is correct and my LED on my Phone changes its state accordingly to the timecondition.
This only happens when you enter a Time where you only need one single day, when you have a Time group with 2 or more days, everything gets inserted correctly.
