I asked 2 questions in post #2. For us to be able to help, you need to show how this occurs without requiring us to debug your application code. You can create a reproduction example that contains nothing except your skeleton showing the problem. However, we no longer develop fixes in 3.8, which is very, very old. Your best bet is likely to upgrade to the latest stable version, currently 4.1. You will need to re-export your skeletons with 4.1 and update your runtime to 4.1 to match.
