LuxCal 5.3.3 - Time in notification message title not always visible

When the event start or end time starts with a 9 (i.e. 9:00 - 9:59), in notification email and SMS messages the start and/or end time is not always visible.
This problem can be solved as follows:
Edit the file "common/toolbox.php" and change line 59
from . . . .

if (!$time or $time[0] == '9') { return ''; }

to . . . .

if (!$time or substr($time,0,2) == '99') { return ''; }
