This happens a lot in Revit — it’s not that your new levels don’t exist in Model B, it’s usually that they’re just not visible because of view-specific visibility settings in the host model.
Here’s the main checklist to fix it:
Check if the levels are visible in the linked model itself
Open Model A directly.
Make sure the two new levels are indeed there, not hidden, and visible in the relevant views.
Ensure they have a view range that would allow them to appear in an elevation/section.
In Model B: Adjust the Visibility/Graphics for the link
Go to the view where you expect to see the levels (likely an elevation or section).
Press VG (or go to View → Visibility/Graphics).
Go to the Revit Links tab.
Set the Display Settings for your link:
Choose Custom → Annotation Categories.
Make sure Levels is checked.
If By Host View is used, switch to By Linked View and choose a linked view from Model A that already shows the new levels.
Check scope boxes
If Model A’s levels are assigned to a scope box that isn’t visible in Model B, they won’t show.
In Model A, either remove the scope box from those levels or ensure Model B has a matching scope box visible.
Workset visibility
Elevation extents
In Model A, the level heads (annotation) might not be extended far enough to intersect your view in Model B.
Open Model A, stretch the level line so it crosses the linked view’s section/elevation line area.
