Unexpected vertical scrolling behavior in Resource View since version 2023.4.5839

Hi,

we're using DayPilot Scheduler in resource view mode with nested columns (one parent per day, and one child resource per day). Everything worked as expected in version 2023.4.5820.

Starting with version 2023.4.5839, however, we noticed unexpected vertical scrolling behavior:
In week view, the calendar now scrolls down vertically for 5 days, and events from Tuesday, Wednesday, etc. appear repeatedly further down – even though they are already correctly displayed in their respective columns.

Here's an example of our columns definition (simplified):

columns: [
  {
    name: "Mon 30.06.2025",
    start: "2025-06-30T00:00:00",
    children: [
      { name: "CT", id: "53", start: "2025-06-30T00:00:00" }
    ]
  },
  {
    name: "Tue 01.07.2025",
    start: "2025-07-01T00:00:00",
    children: [
      { name: "CT", id: "53", start: "2025-07-01T00:00:00" }
    ]
  },
  ...
]

In older versions, each day + resource combination was shown once, horizontally as expected.
In the newer version, vertical scrolling adds duplicate-looking rows, making the calendar hard to use.

We already tried options like:

• heightSpec: "Max"

• rowHeaderScrolling: false

• treeEnabled: false

• different scrolling.scrollY settings

None of them fixed the issue.

Is this a known change or bug in recent versions?
Any recommendations on how to restore the previous behavior?

Thanks in advance!
