Hi,
It is known issue, depends on the item number in the category layout page; things start acting weirdly and this break the harmony of entire website layout. The problem happens because of our VM Template, don't try to enable/disable your modules. They are okay.
This problem has been fixed already. I am seeing that you have purchased our VM Template long time ago, we have updated our VM Temolate a lot since then. Most importantly we have brought 1-page checkout functionality in the shopping cart and the VM Template is now fully compatible with VM2.0.8e. I have already sent you the download link to your email address

Please download the latest version, and re-apply our VM template.
If you did some custom changes in our VM Template don't want to lose your changes, then only upload this folder
/category/
Then this misalignment problem in the category page will be solved by itself.
If the problem persists after updating the VM Template, let me know. I will deeply investigate your website.
cheers.
Flexible Support Team.
