Steps to Reproduce:
1. Go to any portlet that contains the start and finish dates on the filter section.
Home > General > Project Dashboard tab > Schedule Dashboard portlet.
2. Go to Option > Configure > list filter section > layout and add 'Start'/'finish' to selected column
4. Now go to filter fields, open 'start' properties and change Display type to 'Date Range' and click on save and return.
Do the same with the finish date
5. Check the Start and Finish Dates of any of the projects listed, ie 6/1/17 till 9/14/17
6. Filter Start Date Range 6/1/17 till 6/1/17 or Finish 9/14/17 till 9/14/17
Expected result: Projects with the above dates to be filtered
Actual result: Projects are excluded and only included if we filter as Start Date Range 6/1/17 till 6/2/17 or Finish 9/14/17 till 9/15/17
