Additional slug added in front of the Pod’s custom post slug

Hello,
So, i’m using WordPress’ default “Posts” post type for my blog. Since I want all of my articles be organized under a single custom slug, I updated my permalinks setup to “Custom Structure” and used the following rule:
blog/%postname%/
Therefore, all of my articles are nested under the /blog/ slug.

The problem is that this /blog/ slug is being added to all the post types that I create through your plugin, which is not what I need. I need each post types that I create through your plugin be independent and NOT be nested under any other slug.

Can you let me know how I can solve this issue?

Thank you!
