For others with similar issues, this is because the walls hosting the doors are multi-story. You're seeing the bottom cut line of the door.
Just change the base offset of the door to "0'-00" from associated level..
or match the base offset with other doors which are showing correct.
Cheers!
I am also experiencing this issue. I am working on a single story, and the issue is happening on exterior walls but not interior walls. The bottom left leads from garage to exterior, the middle is garage to interior and the right is to the laundry room.
@ericVD22Dis the garage floor level set-down from the main floor level? Do the walls have the same Base Offset and Base Constraint as the doors have Sill Height and Level?
Ensure the door is not offset from the associated level and that the base constraints of the wall and door match. If you have modelled a floor up to the interior face of the wall and another wall to the exterior face of the wall, the lines that are showing may not be the door but the edges of each floor.
