Issues merging pdf documents with Digital signature, signature disappears

I just tried merging documents in Preview. One document had digital signatures. Signatures disappears when merging.

The second problem is the following, I received a pdf via Mac mail. The document has a digital signature.

When I open it in Preview I can click with my mouse on the signature and probably change it.

I use preview om a frequent basis. and this is the first time I am have this issue.

Anybody knows about this issue

What kind of "signatures"? Be specific. Depending on the type of digital signature, it may just get invalidated by doing some operations as expected. What do you mean by "disappears"?

When you open a pdf document in preview and the document has a someone signature (digital signature like an autograph) on the document. Then you try to merge this signed document with another pdf, the signature that was initially disappears.

Ah! It is just the insertion of an image then? I thought it was about a real Digital Signature. Do you understand what a Digital Signature is? Anyways...

This looks like a different problem. I cannot reproduce it ... unless I'm missing something.
