Rollover for ACS symbol attach file label incorrect

Summary

There are some missing visual items in the activiti-app file attach form field for the Alfresco selection.

• the text 'Select the source of content' is not accurate, if the form field is defined 'only' for selection from 'Alfresco' and not 'All sources'. This is regardless of language.

• the rollover/hover text label for the Alfresco symbol (any language) is not defined label

Replication Steps

• create process with form with attach field, set configuration to select all and field to select just from ACS
• publish/deploy, start process, observer form label and rollover

Expected Behavior

• roll over has valid internationalized label
• text in a Alfresco only file attach form should say 'Select Content'

Actual Behavior

• roll over is label is not internationalized or a label
• text says 'Select source of content'
