So, I am using Illustrator 25.0 on a Mac 10.15.7 and when I want to export artboards through export for screen menu, the output file only contains the artboard name. The file name is missing (as prefix).

The process is:
1. I create a document.
2. Draw a rectangle (or anything) in artboard named 'rectangle'.
3. Save it anywhere as 'test.ai'
4. Export the artboard using export for screen as a JPG, with default settings — Ai won't show any file name.
5. The exported file is named rectangle.jpg instead of test-rectangle.jpg

In older versions the exported artboard used to have automatically the file name. Any solution or help?

Thanks!
