Product Rating issue in frontend

[m2webdesigning]

Hi,

I have a rating system enabled for registered user in VM2, But when the user put there reviews with 5 Rating from the product page and once its approved by administrator it shows 2 Rating in frontend rather than 5, It shows correct in backend but it seems its not showing correct rating in the product page.

Anyone can help me please, its been a panic from last week to me, and if any plugin is available for this let me know.

Thanks
