RE: Data entity change name/label
I have an update on this. After a few hours I checked back in DIXF and now I see the entity twice. One with the name being the label and one with the name being the actual AOT name. Remember: this is just in DIXF - in the oData part it works fine.
I changed the label again, and after a while, I now see three.

The source of that dropdown is DMFUtil::lookupEntity and the source is table DMFEntity
I ran a query on the database:
select * from dmfentity where entitytable like 'EMT%'
and sure enough it gave me 3 rows. So I just deleted the ones I wasn't using.
Perhaps it is something from Microsoft's side that they should fix..if I relabel an entity, it should change it on the DMFEntity table
