Digital signature field can't be signed

[traceyc28668387]

I have a fillable PDF we have been using for years, never a problem with the digital signatures until twice now this last week.  I know, you're not supposed to have multiple digital signatures, but that's how my work wants it and I can't change that.  Anyways, twice now the last required digital signature field that the manager signs has been getting a message saying 'This document can't be signed'.  The form has to be filled out again and all digital signatures are filled in and the manager can sign no problem.  All the other 20 of the same forms each day have been working fine as usual and the manager has been able to sign just fine.  The only difference I can see between the one that didn't work in Figure 1 and the one that works in Figure 2 is the order of Revisions are not in order, even though the time stamps say they are.  On Figure 1 Rev 1 is showing as Mike but it should be Alexander as he signed first, but he's showing up as Rev 4.  What could cause the revisions go out of order when signing?  The employee fills it out, signs it, emails it to the Foreman to review and sign, sends to the Foreman 2 to sign, the timekeeper signs, then the Manager signs.  Yes, it's overkill, but I can't do anything about that.  Anyways, the Manager's digital signature field is set to lock when signing and Figure 3 are the names of the digital fields in the original document.  Any help would be appreciated.  I can't find anything on the forums on this issue.

First of all,

I know, you're not supposed to have multiple digital signatures,

Why? If you have a workflow requiring the approval of multiple participants, having a form with multiple signature fields is quite natural.

That being said, it would be pure guesswork to try and resolve the issue based on the information you've given.

Thus, can you share the files in question?

I've only seen unexpected revision orders in the signature panel if either the signature fields had indeed been signed in the wrong order or if a later signer applied not a mere approval signature but actually an author signature. Adobe Reader shouldn't allow that but other software may do that.

Oh thanks, I must have misunderstood a previous reply from a different matter on multiple signatures .

Unfortunately, I can't share the file due to privacy.  That's why I blacked out the last names.  I looked at the date stamps and they were signed in the right order.  It's only one person out of about 20 a day that we've ever had this issue, twice now this week.  I'm lost as to why, but if it keeps happening I'll have to dig deeper as to how they are signing and submitting the form.  Thanks for the reply!

Can you at least share the unsigned form? That might allow us to play around a bit with it and maybe trigger the issue.

Also, do all users sign with Adobe Reader or Acrobat? (The signature field backgrounds look like that but looks can be copied.)

The original form has drop downs with all the employee names on it and I don't feel comfertable sharing it.  I sure wish I could, it make it a lot easier.  They all sign with Reader.

You say that the Manager Signature is st to Lock when signing. But have you ensured that the other signatures (specifically the Timekeeper signature) are explicitly set to "Don't Lock" when signing?

Yes, absolutely
