Can you share a sample file please? You can zip and upload it here. Otherwise I might not be able to help much.

Also give version 3.2.0.0 a try. I doubt it has addressed your issue but wanted to suggest just in case 🤞🏼 .

I believe this is due to list fields with nested struct values. Implementing it has proven challenging.
