Null checkbox not working

[Anonymous]

I have created a dropdown box with a null checkbox as shown on the screenshot below, however, the null checkbox is always greyed out and if i dont select anything on the drop down box, the report does not display any results. Requirements is that the checbox / dropdown box be optional and report should work just fine whether user selects something on the dropdown or not. ANyone know what the solution might be?

Basically i created a dropdown  box parameter based on this query,  requirement is to make this dropdown optional so that users can selectr dropdown items if they choose to or they can skip it and still be able to run the report. Issue i am having is that when user dont select the dropdown items the report output is blank even after they select all the other  parameters. 

f((Date.From([ACT_START_DATE]) <>null ) and (Date.From([ACT_END_DATE]) = null) or
(Date.From([START_DATE]) <= Date.AddDays(Date.From(DateTime.LocalNow()),3))) then "3 Forward" else if
(Date.From([FINISH_DATE]) >= Date.AddDays(Date.From(DateTime.LocalNow()),7)) then "7 Forward" else "All"
