Why does 'WM' mean more to you than 'EM'?  I am interested to know.

It doesn't but you said EastHD should be E HD and EMidHD should be EM HD. That is what makes no sense.

WM should be WMidHD.

If you're looking for a regional BBC One service on Freesat, then I guess you've got the intelligence to understand SW, NW, NE, WM, EM, E, W etc.

Unless you're expecting it to say "BBC One 'down the road 3 miles, turn left and it's the building on the right' HD".

These should be very basic names following the same structure in all regions.  It's common sense in any sort of presentation to do that.

I doubt anyone in the East Midlands would ignore 'BBC One EM HD' thinking it means 'East Middlesbrough' and go hunting for something else.

My point is consistency and the need to avoid unnecessary squashing of names within a limited space on the EPG.
