Modeler V1.02 - Integrity issues - Lost triggers

I’m experiencing recurring integrity issues using Modeler V1.02. Issue description : When updating an Operation Trigger, the tool saves the Operations Trigger but it maps it wrongly to the Object Open Issues Trigger. Then, both triggers are updated simultaneously !!! That’s not the goal. My question is : does someone get the same kind of troubles with the Modeler ? Alternate question : Do you use it or not and why or what else ?
