Bitmap Importing Issues

[CrawfishPress]

Hi, let me say I greatly appreciate this tutorial series (although only on the first video, it looks excellent). However, I'm having a problem doing the filter-unsetting in the Import-Resources section. I'm using Godot 3.5, which may be the problem, or I just might not know what I'm doing. :)

When I import individual .PNG files, the filter-unsetting (set as the texture-default) that you explain in the video - works. But when I drag in an entire directory of .PNG files, it does not apply the filter-unset. Looking at your Action-Resource.zip file in the repo, it contains .import files such as bush.png.import, which, appear to apply their own settings. When I delete the .import files, then import the entire directory again, it correctly applies the filter-unset. So should the .import files be used? Are they unnecessary? Thanks.
