Should be a bug of ESET HIPS

version: ESET Antivirus 9.0.349.15 (32-bit)
HIPS mode: Automatic Mode

Now I have established a all-ask rule like this:
Rule Name: 1 - Ask All
Source: All Applications
Target: All Applications
Action: Ask
Application Operation: Modify state of another application

I have also created another rule which allows chrome.exe to modify itself:
Rule Name: 2 - Example Allow Chrome
Source: %ChromePath%\chrome.exe
Target: %ChromePath%\chrome.exe...
