Show us how this file is built.
Is the something in outline mode?
What does the layer panel show?
How does the brush look?
I told you the other day Id prefer you dont bother responding to my threads anymore. Youre annoying. All you ever do is reply with a tone with a bunch of questions. There are many more people who respond with useful information.
If you want help, then we will need more information as Monica has suggested. We have no knowledge of how the file was produced. Only you know.
