Do not use the name of the entity as the display name of the primary field.

When you create an entity, the primary key field that contains the unique record ID (GUID) has the same display name as the original display name of the entity. If your Primary Field uses the same Display Name, this is allowed because the schema names will be different (the primary key field will be called <prefix>_<entityname>id).

When you are trying to use fields in advanced find queries, charts and workflows, for example, the two fields appear identical, and this could lead to confusion and possible errors. It is useful to be able to rely on the fact that the field that has the same name as the entity is the primary key field in every case. Therefore, we recommend that you select something different, or accept the default value of “Name”
