I am trying to access the Gaps in Register By Date Report and it is saying I have overlapping Holidays, how do I fix these?

If you go to Admin > Config > Core Set Up > Holidays. In here look for any dates that may be overlapping.  For example;

The Easter and Bank Holiday overlap as they both include 22/04/19.

You can either remove the Bank Holiday and leave the Easter Holiday as it is. 

Alternatively you could remove Easter completely and add the period in again as a new holiday with an end date of the 18th April.  

Please note: These overlapping dates may be in previous years so please check all entries here.
