Advanced Excerpt plugin does not work properly

hi ,

i an making a demo gaming website to show to a client on worpress by taking gamepress theme….everything seems good but until i installed a plugin known as “Advanced Excerpt”….

the problem is that i set 15 words for excerpt in post but it properly gives [read more] link after 15th word and even shows that full post when we click on that link….

but the main problem is that it shows [read more] link to all the post and even on the post which is less then 15 words

you can check my website on :

hence i want to remove the link on post less then specified words in my case its 15 words …

hope that somebody finds the solution.
