Error in updating posts

I have been using this plugin for over a year and it is great. But before this, i used WP Link Preview in my 4 posts to generate links with featured images. Now, when i’m trying to update those posts using this plugin, it sucks. It erases all the text before the link preview. I have tried erasing all the text and everything from the post and rewrote it but when visual preview link is inserted, all the content before the link is deleted automatically. Kindly provide a fixture for this kinda bug. Thanks.
