[Plugin: WP Limit Posts Automatically] display by words limit

Another question on WP Limit Posts Automatically plugin.

If I set options so that the posts are limited to 400 words, then in my main page, the posts are displayed all in italic fonts. If I click the post, then each post is normal without italic, but on main page everything is displayed with italic.

From page 2/3/4 of main page (those pages I get to by clicking “Previous posts”), the posts are randomly 1) changed to italic or 2) have deleted mark (a black line across sentences) or 3) all messed up in a table column.

In short, under limit by words option, the formatting is completely lost. I am if I am the only one experiencing this problem. Also curious if there is any way to fix this problem.

Thank you.
