1) define a new table under connections.
2) add this table to the business tables section of a business model
3) define a relation between the newly added table and an already existing table.
4) change the general/name of the table for a specific locale.

The change is not propagated to the table as seen in the business tables section of the business model

Are there specific reasons why this change is not propagated to all tables in the business model section?

To me it is very unconvenint, as 1 mistake made when defining the tables, can cause a change in a multiple of tables in the business model section. Especially when you make the mistake in tables defining "common" data that is used everywhere.
