After adding validation information, Adobe Reader says Signature is not LTV enabled

Hello all.

I’m trying to use Apache PDFBox 2.0.17 to ellectronically sign some documents, including LTV information.
I have followed the examples provided in class CreateSignature to sign the document, and in class AddValidationInformation to add LTV information.

After adding LTV information, size of the PDF file is increased from 230KB to 252KB, so additional information was added in deed.
But, Adobe Reader in Signature panel still shows the label „Signature is not LTV enabled...“.
Can you please check the attached files and figure out what’s wrong?

Best regards,
Predrag
