The differences you are noticing is expected.
On 1.26.6 the shift view only took audio codec and audio channels from the metadata but the movie details preferred the file name for both.
On 1.26.7 the shift view was changed to prefer both these values from the file name too.
What will be 1.26.8 fixes a problem with identifying DTS-X.

I need to figure out why the file name is making it see 2.0.

Sorry about that.  You've told me this like three different ways now.  I don't know why my mind keeps going there.

Best,

Could you try the same test I did here.

1. Create a new folder with any name, I used Kodi Test
   
2. Create another new folder inside the one above and name it The Bourne Supremacy (2004)  Copy and paste from this from here.
   
3. Create a new file blank test file in the above folder.
   
4. Rename the file to The.Bourne.Supremacy.2004.UHD.BluRay.2160p.DTS-X.7.1.HEVC.REMUX-MyRIP.mkv  Copy and paste from this from here.
   
5. In kodi add a new video source using the folder created in step 1.  Set the content to Movie and Local information only and save
   
6. Browse this folder with the infowall view and select the file made in step 4.
   

What icons do you get?

Also just noticed that I am not getting the codec info...
