I don't see the option to "Send" a sign document.

I'm trying to send a document for signing on my iMac (using Safari). 

I follow the instruction on completing the process and fill in the required fields. When I finish - there is no 'Send' to select in the upper right corner. Only option is to 'save a copy' or 'replace original'  - and both of which will bomb me out and loose all the fields I've set up ready for signatures.

Has anyone else had this problem?

Have been using this programme for a number of years but never had this problem before, and now I can't use it at all which is a real shame.
