Hi Garry Garry,
Thank you for your interest in Vacation Request!
The release of Vacation Request mentioned in your bug report is more than 2 years old.
There may have been some issues with that release back then.
Please upgrade to the current release (2.2.8) and see if the bug persists.
Make sure that you backup your current production instance prior to the upgrade.
Pay special attention to the documentation included with release 2.2.8 and all should go well.
HTH,
Bob
