I have strange text beside the text input boxes named for example

Not sure how to change?
I am afraid of that reinstall will loose content in the database.

Please suggest appropriate method

You should tell us your version of SuiteCRM, PHP, etc.

I understand this is a new installation?

Normally when you see many places in the application with “undefined” labels or with “LBL_*” labels, those are permissions issues on your installation. You should make sure you set the correct permissions before installing.

EDIT - I deleted some of your other posts which looked like a repetition. We can handle all these label issues here in this post. Thanks.
