This is not an issue. This is how VSAPI (Virus Scan Application Programming Interface) detects and clean a file.
Example:
SA detects a file that has been infected multiple times. When VSAPI detects this file for the first time, it will run a scan and return the first scan result (action taken). If the file is still not clean after the first attempt, VSAPI will run again another series of scan to clean the file. As a result, SA will display the second scan result.
