Data Table – Misbehaving Lines

Hello:

I am having a trouble with Data Tables on my site. When viewing a page with one or multiple tables at least one of them will have some lines duplicated and moved to a side.

If I refresh the page, it will fix itself

BUT a different table on the same page will show the same problem

Any help would be much appreciated.
