BUG Incorrect display of the calendar

https://voltdetailing.1b.app/app/calendar/?ok=1 Є processes, at which the hour is "scheduled" and "visonati until", for example, from 14:00 to 18:00 І є process, on the same day, for example, from 15:00 to 17:00 Then the processes from 14 to 18 will cover up the processes from 15 to 17 again, which makes the calendar difficult. It was necessary that the process, yakі go after the ones in front, they got up "from above" quietly, before https://ibb.co/X3Xd0G9 And yet, I think, not all processes are displayed on the calendar of the correct date, in the fall at the time of "planning" and "visonati until" https://ibb.co/vzgHRLq
