Problems after Confluence import

Hi everyone,
I installed the newest version of Xwiki and the FilterStreams + Confluence XML extensions. I tried to import a small package from Confluence via a .zip file.

The import worked. Now there are two problems:

  1. Some pages give me a message that there is no valid license for ProMacros. Is there a free alternative to ProMacros? I’m not sure under which circumstances the message gets triggered.

  2. Xwiki created a section under Navigation which contains all pages in alphabetical order, which means that the previous structure of the articles has not been included in any way. Is there any way to keep the Confluence structure?

I tried using Nested Pages Migrator to save the hierarchy. When detecting breakages it says that if I dont migrate my pages, 300 pages will lose it’s parent. But when I say Compute plan it notes that there is nothing to do. Execute plan is greyed out.
Did I do something wrong?
