Zoho Writer "finish and merge" greyed out

Zoho Writer "finish and merge" greyed out

On my login I can see the Finish and Merge button and can see the final letter, but the other users can't.  They can open a template that I created but the Finish and Merge button is greyed out for them.  Is there a setting I need to turn on to allow them to use this feature?  They are starting the same way I do...we pick a lead and from the more actions choose mail merge.  It then prompts us for the letter template to use and brings up zoho writer.  I can see the Finish and Merge button and use it, but they can't.  Thanks for your help!
