As seen in the attached screenshot, Revit does not update the gross area schedule. On the left we see a seperate .RVT file that is linked in on the right. The link is saved, closed, and reloaded into the file on the right. The schedule does not update.
I feel your pain. We've noticed the same thing happening in our 2019s. Close and reopen resolves for us. I suspect a hotfix will be coming down the pike.
the worst part of this is that I removed the link, and when added back in, it is still pulling the outdated information. In the linked file, there are two area types, and not the one listed 'CR-102' isn't found in the original linked file anymore.
Revit was pulling rentable area information instead of gross. I found this out by creating a rentable area view and found that someone before me had started and later deleted the rentable area view, creating the anomaly.
Fix:
-create both rentable and gross area views in addition to double checking existing views while searching for the anomaly
