Error when adding a second signature via adobe, if there is already 1 signature via pdf-signer. (the signature byte range is invalid)

Hello, I need help. This problem is also present in node-signpdf.

After the signature was signed by the pdf-signer library. I'm trying to put 2 signatures using Adobe Reader. Before restarting the program with an open PDF file, everything works fine, but after closing the program and opening it. The signature is delivered via the pdf library-the signer stops working (the signature byte range is invalid).
