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,
