How can I fix an incorrect SQL field in Recurring Contribution View?
That particular table is exposed to Views by the Core CiviCRM module, not CiviCRM entity.  I haven't exposed that entity to Drupal yet, but its on the todo list. 

I have added some code to CiviCRM Entity to fix this...

Its available in the latest -dev release from the CiviCRM Entity project page
and will be in beta7 when it is released
