Scans showing previous scan results as well

Hi after doing a few full scans Avast seems to be displaying the previous scan results as well as the results of scan. These include a file corruption I have repaired a few days ago and multiple copies of the same Skydrive folder. I have checked if the file is corrupted again and it is not, any help would be appreciated.

hope some one will notice.
actually this bug will occur when we clean scan history and will not occur until u clean all scan logs.

just read my post to know how to create this bug.
it is too annoying.
