Built example successfully. But, I have many "Missing Block" when I open *.grc files

I have built the LTE master in my Linux machine. I have been able to build all successfully. After I open any of the *.grc file, I have many "Missing Block". In the block library list, I have a lte library, and I have a good amount of ready to use block in lte library. See attached screenshot.

Did I do anything wrong or did I missed something?

I found the solution myself. I skipped the generate part. After generating the lower level blocks one by one, the problem is resolved.
