Are you using the default catalog? Could you pleas let us know the version for OpenPlant Modeler? Also it would be great if you write few steps while placement.
Thanks in Advance!

I tested this with same environment as that of yours and i am able to place the components in a newly created OPM DGN with no issues. Please see the snapshot below.
As per information you provided, I suspect the DGN that you are working on. May be the ports are being matched incorrectly. Is it possible for you to share the DGN?
