2. To Reproduce

1. Go to '...'

AL code snippet that demonstrates the issue or a link to a code repository the developers can easily pull down to recreate the issue locally.

Note: Because the developers need to copy and paste the code snippet, including a code snippet as a media file (i.e. .gif) is not sufficient.

3. Expected behavior
Save the file with al formatter!

4. Actual behavior
A clear and concise description of what happened accompanied by images, animations, or a link to a video showing the issue occurring

I have the same issue. Not all files in the project seem to be affected.

We will look into it but without proper repro steps chances are slim that they will get fixed.

I find this is often the case with very large files (or projects). The only way around I have found is to reload vs code.
