Bug: Editing an event triggers “Timeranges cannot overlap error

Issue:
When editing an event and saving without making any changes, Events Manager can display the error:

“Timeranges cannot overlap with each other”

This happens even when the event has only a single time range.

Steps

1. Create and save a standard (non-recurring) event with one date/time.
2. Edit the event.
3. Make no changes.
4. Save.

In some cases, the save fails with the overlap error and the UI shows two time ranges.

Notes:

• The issue is intermittent.
• Server cache state appears to affect reproducibility (after purging cache, the issue is harder to reproduce).
• All caching and optimization were disabled during testing, so this does not appear to be a browser cache issue.
• The error suggests the validator may be seeing duplicate timeranges during the edit/save process.

“culprit” callout is:

• events-manager/classes/timeslots/timeranges.php
  • get_post() lines 254 to 271 (potentially duplicates timeranges on edit/save)
  • validate() lines 292 to 308 (throws the message)
  • has_overlapping_timeranges() lines 318 to 339 (flags duplicates as overlap)
