Include empty date values in table when changing date slider

Hi some_bih  : I tried checking this option and I am still not able to see any data with null dates when the dates in the slicer is changed.

Please note that we do have data in the dataset for the missing dates, just that the date field is empty.

There are other fields as well in the report. The above is a sample data with 2 fields.

some_bih  - Thanks for the link but I am unable to fix the issue.  Below is the code from  the link provided.  I have tried to replace the [Date] field from the code with the [NEXT_REVIEW_DATE] in my case . 

Also, I was unable to get to how Slicer[Allowblank] is used. Could you please share a sample pbix file if possible.

measure =
var _min = minx(allselected(Date,Date[Date])
var _max = minx(allselected(Date,Date[Date])
var _maxval = if(isfiltered(Slicer[Allowblank]),max(Slicer[Allowblank]),blank())
return
if(_maxval ="Allowblank",
calculate(sum(table[Value]),filter(all(Table[Receive Date]),Table[Receive Date]>=_min && Table[Receive Date]>=_max && isblank(Table[Receive Date])))
,
calculate(sum(table[Value]),filter(all(date),Date,Date[Date]>=_min && Date[Date]>=_max))
)

Hi some_bih - I have a sample test pbix file. Could you suggest how I can share the file here

some_bih  : As I am having limitations to access to upload files outside f client network, I am pasting sample data here.

NEXT_REVIEW_DATE is the field used in the slicer.
Sample screenshot:

Whe, I change the slider , along with the selected dates, I should also be able to get the records with no dates as well.

Hope these details will help to replicate the issue.

Hi some_bih : I have set the data types as in the report. Blank dates are visible only when the left side of the slider is unchanged and right side slider is changed.

We would like to see blank records when right or left slider is changed by user.
Inital View when the slider is unchanged:

View when right side slider is changed, We get blank dates as well:

View when left side slider is changed, blank values are disappeared

some_bih  : User is looking to have a date filter with range and a drop down may not be a best option for them as the no.of dates are too many.
