The existing mergefield "mAuthorInstituteCompletem" automatically changed the first letter uppercase and the rest of the word lowercase, eg:
Julian-hein west MUeller --> Julian-hein West Mueller. In addition specific words like "for" were ignored.
If you don´t want to use this automatic upper- and lowercase automization you can now also use following mergefield "mAuthorInstituteCompleteOm". This will not change the existing text.
