When multiple drawing views exist, it is important that their balloons display the same numbers for the same parts. To do this, the drawing views must be linked to the same BOM. To do this, right click on the drawing view and click on Properties.
Then make sure the checkbox "Link balloon test to specified table" under the Balloons section is checked. If you have multiple BOMs, click on the dropdown menu to select the correct one.
After clicking OK, drawing views that are linked to a particular BOM should display the same balloon numbers for the same parts.
