Hi,
Unfortunately in the current version of the Record Browser (RB - the engine that controls most of epesi modules), you can not modify easily mandatory fields (those fields are created by a developer). Only custom fields can be edited and modified. We are aware of those limitations and future RB version will address this issue.
However you can still fix it manually. I don't know what database engine you are using, but here are instructions on how to do it in MySQL using SQLyog (http://www.webyog.com/en/):
Open your epesi database, table "company_field" which holds definition of fields in this module and change "visible" from 0 to 1 - this controls if the field is visible in Browse (table) view:
Here i turned both Address 1 and 2 to be visible:
