Hi,
Thank you for the details, it helps a lot!
If I understand correclty, this is not printed correctly. The problem is, that this is not related to our plugin in any way. That is not printed by Ajax Search Pro.
Just to be sure, I have deactivated the plugin temporarily, and checked again, the output did not change. I’m afraid you may need to contact the theme or plugin author of that feature. They may know how to change that.
