If you’re trying to edit rates and notice that a day-of-week checkbox is disabled and won’t let you uncheck it, this is expected behavior.
Why this happens
On the left sidebar, Birrdi shows a list of days from Monday–Sunday.
The day you currently have selected in that sidebar is considered the active day.
Because of this:
The active day cannot be unchecked in the day-of-week selector
At least one day must always be selected to apply rates
This prevents rates from being created without a valid day attached.
Example
You are currently viewing Monday in the left sidebar
In the day-of-week checkboxes, Monday appears disabled
This means:
You cannot uncheck Monday while you are on Monday
This is working as intended
How to apply rates to a different day
If you only want to add rates for Tuesday and Wednesday:
Click Tuesday in the left sidebar
The previously disabled day (Monday) will no longer be forced once you switch days.
Key takeaway
The disabled checkbox always corresponds to the day currently selected in the left sidebar. To edit or exclude a specific day, simply navigate to a different day first.
