The problem is that Finder doesn't differentiate different file types properly. Everything gets grouped as Other.
It doesn't solely use file extensions for kind. It uses Uniform Type Identifiers to determine the type of content.
Open a Terminal window and type the following, leaving a space after the command, but don't hit return, yet.
mdls
Drag one of the files into the Terminal window and hit return. It will list all of the metadata attached to that file.
Here is an example of part of the output for an Excel Spreadsheet:
kMDItemContentCreationDate = 2012-10-27 01:59:01 +0000
kMDItemContentModificationDate = 2015-03-18 22:19:03 +0000
kMDItemContentType = "com.microsoft.excel.xls"
kMDItemContentTypeTree = (
"com.microsoft.excel.xls",
"public.data",
"public.item"
)
The ContentType is where it gets the info for the Arrange By information.
Now, a text type document is just a document. It doesn't have a special category, so those will end up in Other.
My guess is there is something still wrong with your spotlight index. You can delete the whole thing and it will rebuild it automatically.
Here is the command to erase the index on the startup volume. If you need to erase other volumes, replace / with the path to the volume.
sudo mdutil -E /
sudo temporarily elevates your privileges and runs the next command with those privileges. The rest of the command erases the index on the startup volume: /
