Files section - files with default template not visible

Today while upgrading one of my Kirby websites I noticed invisible files in default files section. I will try to explain what I mean.

I downloaded the latest plainkit and created two simple files sections:

default_files:
  type: files
  template: default
image_files:
  type: files
  template: image

And two corresponding file blueprints:

# blueprints/files/default.yml
# Does not necessarily have to be limited to document. I tried it without "accept" option too
title: "Default template"
accept:
  type: document
# blueprint/files/image.yml
title: "Image template"
accept: 
  type: image

Now, I can upload files without any issue. Even the file type restrictions (if set) work as expected. But after uploading any file to the default_files section, nothing is displayed. The file uploads correctly, but somehow the section does not show it. And I cant figure out what is wrong.

default is just a fallback template, if you give your template a specific name other than default, it will work as expected.

Thank you for clarification, Sonja! I would swear it used to work - that is files not disappearing from the section after upload. Nevertheless, I think I will stick with the default fallback template and just modify the section.

default_files:
  type: files
  query: page.files.filterBy("template", "!=", "image")
image_files:
  type: files
  template: image
