Problem occurs only in EE version, in Platform version, headers are the same as in requirements (besides the difference between Code and Language code).

Prerequisites - none

Steps:

1. Go to Admin > Languages/Sections
2. Click language/section link

Actual result:

Loaded language/section details view with following table header

Language name: | Language code: | Language ID: | Language enabled:

Section name | Section identifier | Section ID

Expected result:

Loaded language details view with following table header:

Name | Code | ID | Enabled

Like in Requirements

Expected result for sections is not very clear for me - because of consistency purposes headers should look similar, but requirements specifies headers as they are now (in this case we have problem with headers in P version as long as they are literally "Name", "Identifier" and "ID"). Anyway we have different section headers in versions P and EE, and we should change that.
