Gannt Limitation - Gaps in the bar

[gvdev22]

Hi folks

I want to use the Gantt chart to display all machine activities during a 24-hour shift.
I have between 10 and 20 machines, and each one can perform around 50 tasks that fall into 4 different types of activities.

Example:
Machine 1 could start with a Task Type 1, then move to Task Type 2, and then return to Task Type 1… or repeat Task Type 1 multiple times.
Each task can take seconds, minutes, or hours to complete.
I want to display the Gantt chart by hour.

The problem:
The Gantt chart is showing gaps in some of the bars, either in the middle or at the end, leaving blank spaces.
However, when I check the data in table format, all the rows are there. So, this appears to be an issue with the Gantt visualization.
