Yes, it was always there. What version of Aurelius you were using before? Are you saying with Aurelius 5.5, the error happens in Delphi 11 but not in Delphi 10.4? Can you please give more details about the exact Aurelius/Delphi versions that work and do not work?
If possible, could you please send a small project reproducing the issue? That's a lot of fields!
