Hi w.bonazzoli,
This issue has been fixed. I have tested it and can confirm that the checkbox no longer turns into a radio button during the merging process. The fix will be part of the next updated package set to release at the end of the month.
To get notified for the next official SDK release you can join our Discourse Announcements channel.
For platform specific notifications, such as Nuget, NPM, CocoaPods, please see the respective Apryse product documentation page.
Thanks,
