Night shift 22:00–06:00 gives an "overlaps another shift" error in the web version

[LogicAutomation]

We run three shifts: 06:00–14:00, 14:00–22:00 and 22:00–06:00. I moved our plant to the Proveris OEE web version last week and I'm setting the shifts up again under Development > Shifts. The first two saved fine. When I add the night shift with Start Time 22:00 and End Time 06:00 I get this message:
"This time range overlaps another shift. Shifts cannot cover each other; they may only meet at the end of one and the start of the next."
I don't see an overlap on paper. I tried 22:00–05:59 and it still complains. I also tried creating it as two shifts (22:00–00:00 and 00:00–06:00) but then the shift reports are split in two, which the shift supervisors don't want. Does the web version support a shift that crosses midnight, and what am I doing wrong?

[Technical Support]

Yes, a shift that crosses midnight is supported, and you should keep it as a single shift. When you enter an End Time earlier than the Start Time, the form shows the note "Crosses midnight (continues into the next day)." That is the expected behaviour for 22:00–06:00.
The overlap error almost always comes from another record that is already in the list, not from the night shift itself. Please check the following:

1. Look for an old or duplicate record. Open Development > Shifts and review every row. A common case is a leftover shift from testing, for example "Night" saved as 22:00–07:00 or a "Day" shift saved as 05:30–14:00. Either one covers part of your new range.
2. Remember shifts are global. In the web version, shifts are defined once and apply to all machines. A shift someone created "for one line" still blocks the time range for every line.
3. Touching is allowed, covering is not. 14:00 end and 14:00 start is fine. 14:00 end and 13:55 start is an overlap.
4. Names must be unique. If you see "A shift with this name already exists.", edit or delete the old record instead of adding a new one.
5. Check the result. After saving, open Shift Monitoring, pick a machine and use the "Previous shift" / "Next shift" arrows to confirm the night shift is attached to the right date.

Shift ranges define the planned production time for OEE, so a gap or an overlap directly changes Availability. It's worth taking a minute to make sure the three shifts cover exactly 24 hours.
