Symantec blocking executable after restoration from quarantine

Hello, I want to submit a strange behavior in Symantec Endpoint Protection 14 build 1904 on Windows that could be a bug.

Recently one executable file of an our internally developed program is being detected as SONAR.AM.Eg8 and afterwards quarantined.

If I restore the quarantined file to the original location and afterwards I execute the same file, Symantec blocks the executable file without any warning message box or any popup.

I know for sure that Symantec is blocking the file because if I disable Symantec Endpoint Protection and I execute the file again, the program starts.

I wonder if I am the only one experiencing this weird behavior and if this is a known bug.
