Can't add attachment to an email send from the Enterprise module

Can't add attachment to an email send from the Enterprise module

In most modules, if there is an file attached in this module, I can compose an email from this module and add a attachment file using the "From record".




But in the module "Enterprise" I can't.

Even if there is a attachment in a enterprise record, when I click on "From record", I'll get a "No attachment found".


Why?
thanks
