Question - How can I correct registers with gaps in holidays?
Answer - This is likely that the date range hasn't been set up correctly. Holidays must be set from their "start" to "end"date. i.e the first day of the holiday, not the day you broke up from school.
To correct this, remove the current holiday and add it back in and make sure you enter the FIRST date of the holidays and then the LAST. Mark the following day as TRAINING (if you have an INSET day on that date)
