odt_style comes with "Print" global actions which allows getting the default form as ODT and convert it to selected format and DMS comes with "Print" actions which return a PDF of the document content.
As a result, when user try to use Print, they have the same action twice with no way to know which one is which.
This is detected by CodingStyleTestCase.test_DuplicateActions, but only for configurations where both erp5_odt_style and erp5_dms are installed, which is not the case in coding style test suite which only install the miminmal dependent business templates.
