I used the online interface. Uploaded file for signature (using Mac, Ventura 13.1. SafariVersion 16.2 (18614.3.7.1.5)). Placed signature box for signing party. Felt uncomfortable as it didn't look normal based on my usual experience of the software (the default UI has changed). Clicked button which says something like "switch to classic interface". Page appeared blank so placed signature box again. Hit send.

Expected result: Signer should receive file and sign once.
Observed result: Signer received file and was made to sign twice.

You can see two signatures overlayed in the signature area. The audit report for the document, however, only indicates a single signature.
