Error after installation of OpenCart module YML?

59d3ad2a80258547732886.jpegGuys such a trouble, set the export module YML, and now I can no longer see the page "promotion Channels". Writes that page not found. I have version 2.0.3.0. The module itself was installed, but in the Modules tab/Modifiers next to yandex module writes that "Converted to 2.3.0.2". I understand that the error due to the different module versions, and website ?
