Wanted to test if all is working with few schematics to use later but no sadly as can see down.
Tried few thinks to work it out but still same think. Its not only this one cause I tried few more schems to see if they will work but it happens for all of them so no idea what else to do with it

It seems like you have a non-.litematic schematic (since it says Converted schematic), so it's possible the format wasn't recognized correctly or it's broken somehow. Can you send some of those schematic files? Where are they from?

Yes these were converted schematics from minecraft-schematic which I have done in previous version but cant get to work now.
They are from minecraft-schematics
Maybe Im dumb or they just dont work with it
Did these as tests
