I have differences in the number of employee requests, I can’t see them all.

Check if you have a good filtering setting, you should probably extend the date range in the list of requests.

Example:

The Holiday entitlement report shows that employee has used 6 days of his holiday limit.

However, after going to the List of request, we can see only one request.

It is necessary to extend the date range – thanks to that we will get a correct view of all request.
