Text data on a formula row in Data Forms

Summary:

There is a Text appearing in a cell on a Formula Row in a Data Form, that I don't know where it is coming from.

A scenario has been created to enable users to add a Text / Comment.
When I was using this scenario in another data form. A text appeared as read only on a formula Row!

It does appear in multiple periods
It doesn't appear on all the formula rows
It does appear on all the entities
There is only a format validation set on the row

Any suggestions where to look for where it can come from very much appreaciated!
