Issue/Introduction

You are creating a negative business rule (ex- Location ≠ Chicago).  When using this rule and the field is null, it does not work correctly.  If the value for the field is null, then it does not match the rule so the rule should be in effect.

Steps to Reproduce: 

1. In MUX, go to Administration>>Blueprints
2. Copy and rename the Standard Project blueprint
3. Open blueprint and click Edit
4. Click on Rules
5. Create a new rule
   • Target Object=Project
   • Rule Type=View Page
   • Filters=Location≠Chicago
   • Actions=Hide Sections
   • Select = Settings
6. Save
7. Go to Projects Workspace
8. Using the Column flyout, add Location and blueprint to the grid view
9. Add a new Project with the required information and Location as Chicago and the blueprint you just created
10. Open Project and go to properties page
11. Note the Settings section is there
12. Go back to grid view and remove Location so that it is blank
13. Open Project Properties page

Expected Results: Since Location does not equal Chicago, Settings should not be visible

Actual Results: Settings section is visible
