After project upgrade, the duplicate functions from the source version are getting transferred in the newly upgraded version
TDM Version : 18.104.22.168
FDM Version : 22.214.171.124
Release : 4.10
This issue was addressed in version 4.10.98. As your version is the latest version, it looks like these masking functions are duplicated before the product upgrade.
You can test the upgrading the version which is not yet affected by this issue. or Delete the duplications first before upgrading the project/version.
