Description:
When I try to synchronize my model Workbench, sometimes generates code like that:

SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='TRADITIONAL,ALLOW_INVALID_DATES';

I already have all the mentioned tables (and some others). Why Workbench suggest me to remove existing tables??? 
The thing is that it happens each time I switch into another model, synchronize it and than come back to the first model.

----- Developer Notes -----

MySQL Workbench CE for Mac OS X version 5.2.44  revision 9933
Configuration Directory: /Users/wmocarski/Library/Application Support/MySQL/Workbench
Data Directory: /Applications/MySQLWorkbench.app/Contents/Resources
Cairo Version: 1.9.1
OS: Darwin 12.2.0
CPU: 4x Intel(R) Core(TM) i7-2677M CPU @ 1.80GHz, 4.0 GB RAM

How to repeat:
1. I run Synchronize model_customer -> no changes
2. I switch into another model_other
3. I run Synchronize model_other -> no changes
4. I switch again to model_customer
5. I run Synchronize model_customer -> many (as above) changes !!!!! I rejected synchronization.
6. I re-choose again model_customer (having it still opened)
7. I run Synchronize model_customer -> no changes !!!! 

I don't understand it, but it works like that. 
It's pity to say but at the moment Workbench should go back to beta stage and should not be recomended in production environment. Current version works much better than previous one, which had all the time index naming problem, but it's still unstable.

Hello.
Can you please provide a SQL Dump and a model where you can reproduce this error?
Thanks.
