Problems with edge meshing in one edge
 

Hey there!
I am trying to mesh MDA 30P 30N multi-element airfoil. I am facing a problem in meshing a particular edge in the block. when I am increasing the no of nodes from 2 to say 20 half of the block disappears. I have tried exporting as Unstructured mesh in fluent but still, it's showing only half the mesh. The problem is with the edge between the trailing edge of main wing the the leading edge of slat. I will be grateful if anyone can help me. Please let me know if any more screenshots are needed!

I was able to do it, there was an extra node on the top side of the slat.
