FILTER NOT WORKING IN SSRS

Steps taken in creating my filter:

1) I created a parameter called TemporaryPermanent.
 In "General",
  Name: TemporaryPermanent
  Prompt: Temporary / Permanent
  Data Type: Integer

  "Allow Multiple Values" is checked

 In "Available Values",

  "Specify Values" is checked

  I click "Add" button
   On Label, "1 - Temporary"  Value = 1
  I click "Add" button again
   On Label, "0 - Permanent"  Value = 0
 
2) I right click on Tablix, I selected Tablix property,
 In "Filters",
  I click "Add"
  =Parameters!TemporaryPermanent.Value(0) is in Expression
  =Integer as Data type
  =Operator is IN
  =Fields!TemporaryPermanent.Value as value

3) I preview the report,
 I select 1 from the drop-down Temporary/Permanent filter and the filter WORKS.

4) I preview the report AGAIN,
 I select 0 from the drop-down Temporary/Permanent filter and the filter WORKS. 

5) I preview the report AGAIN,
 I select (Select All) from the drop-down Temporary/Permanent filter and the filter is NOT WORKING.

 The report ONLY returned "1 - Temporary" BUT NOT "0 - Permanent"

 I double check my operator to ensure that it has "IN" as an operator and it is.

 Thank you in advance for the help!
