Some content does not appear in wiki

On a lot of pages some content does not appear

For example here:

Under the “Extracting DBC, Maps, VMaps & MMaps” all I see is a “Unknown macro: ‘localtabgroup’” instead of the instructions

See here

Either the content is lost or nobody has time to change it.
