Data in CSV uploads successfully, but it is not visible after upload.

Question

Hi,
I am using Apex 3.2 on Oracle 11g.
This is an imported application for which I am making changes as per my requirements. As I am new to Apex and even SQL, I request forum members to help me with this.
Please find below the old code for uploading data from CSV. It displays only 6 columns - Database Name, Server Name, Application Name, Application Provider, Critical, Remarks. This was successfully uploading all the data from CSV and that data was visible after upload.
OLD CODE:_

Please find below the new code (which I modified as per my requirements) for uploading data from CSV. It displays 17 columns - Hostname, IP Address, Env Type, Env Num, Env Name, Application, Application Component, Notes, Cluster , Load Balanced, Business User Access Mechanism for Application, Env Owner, Controlled Environment, SSO Enabled, ADSI / LDAP / External Directory Authentication, Disaster Recovery Solution in Place, Interfaces with other application.
This is successfully uploading all the data from CSV, But this uploaded data is not visible in its respective tab.

Hi,
You can see the installed dictionaries and change between them by right-clicking and choosing '''Languages''' inside a live text box eg. the box you are in when replying or right-clicking on the '''Search''' box on the top right corner of this page and choosing '''Check Spelling'''.
