Very easy. Glad you asked.

Step 1: Right Click the .BIM file and select View Code

Step 2: Ctrl+F to find __Count of Model

Step 3: Comment the entire Command block that defines this measure

Step 4: Save the change made

Step 5: Now open the .BIM file again --> Build -->Deploy

Note: This is a default measure auto created having value as 1

Hope this helps. Feel free to ask anything you wish.
