This is our third bug-fix release for MPS 2021.2. You can find the complete list of bugs fixed in this version here.

The problem was happening because the stereotypes (e.g. @generator) were being lost after merging models. The issue is fixed in this version 2021.2.3. If you encounter this bug while using a previous version of MPS, please add the stereotype manually to fix the issue. DOWNLOAD MPS 2021.2.3 Please report any issues you find to our i
