DGN Import does not work

Welcome everyone,

I have a DraftSight Professional 2018. Tried to import DGN files and everything seems to go right, I get a message "DGN File imported as block" but nothing is actually imported. Did Zoom / Fit and nothing there. Did Select / All , nothing there. Tried a few different drawings, no success.

When I browse the dgn drawing I get an option in "Select a design model" : 3D Default, Key Plan and 2D Default. None of them work.

Any advice would be appreciated.

Thank you
