Issues on 2D sheets disappear after update

[gianni.fostier]

I have placed issues on a Revit workshared model, but not on the 3D model, rather on the 2D sheets. After an update, some of the issues have disappeared, while others remain. The update itself didn't involve much, only a CAD link was added, nothing was removed. At least 20 of the 30 issues have disappeared... How did this happen?

When I look at a previous version, I do see the issues in the correct place.

Hi @gianni.fostier 

Can you see the issues in the issues tab?

The issues that are missing have the placement attribute defined?
