Error when I try to use 'Copy offer' feature

Content (required):

Hi,

I tried to use 'Copy Offer' functionality. I selected external candidates who don’t yet have a job offer; I selected the Copy Offer Action; In the 'Offer to Copy from Candidate' field I selected the Candidate who is in the Offer phase, however when I click on Submit I display the error message 'The value must be a number' (see the screenshot).

Hoping someone has some suggestions.

Thanks a lot,

Alberto.
