Cannot view or change the category when editing an event

[omarhraste]

Description:
When editing an existing event, the “Category” field is not visible or editable (previously selected in the creation). This prevents users from knowing the current category or changing it, which limits the ability to update or correct event details.

Steps to Reproduce:
1. Open an existing event for editing
2. Look for the “Category” field
3. Notice that it is either missing or not editable

Actual Result:
The category is not shown and cannot be modified during event editing.

Expected Result:
The category field should be visible and editable when updating an event.
