Steps to reproduce:
1. Create trigger with:

• generation mode: multiple
• tag name and value: Tag1 Value1

2. Make first problem event
3. Create event correlation with:

• condition: Old event tag Tag1 <> Value1
  or condition: Old event tag Tag1 not like Value1
• operation: Close new event

4. Make second problem event

Result:
Second problem event resolved by correlation rule
Expected:
Second event stay in Problem, because tag name and value doesn't match correlation rule.

• in old event: Tag1 = Value1
• in correlation rule: Old event tag Tag1 <> Value1
