SANDBOX says it isolates but its not ***

Ok so I made a .bat file to delete a text file for testing and I run the .bat file and it deleted the text file the sandbox pops up and says it was isolated and blocked and gives me options to keep it sandboxed or not, so i chose keep sandboxed but the file was able to do the damage so really the sandbox did not isolate the bug I ran this test on a few machines and made more files and they all let it do the damage can u please check this out because thats a major flaw
