The Reverse mapping field naming algorithm treats column names with mixed case letters - upper and lower case (like IMDGClass) slightly different than column names with all letters with same case (like UUID).
In the first case only the first character is converted to lower case, so IMDGClass is converted to field iMDGClass and in the second case all characters are converted to lower case - so UUID becomes 'uuid'
You can neverthless change this default field name in the wizard. The property name is changed accordingly.
