Different behaviour in R6.5 and R7 text fields

I am having trouble between the two versions. I use ordinary text fields to store some messages. In R7, the format of the text (including line breaks etc) is maintained, but if I open exactly the same form/field in R6.54, the format is distorted, without line breaks, as soon as I save the design.

Is there something I’m missing? I haven’t seen any documented change in the storage of Text fields between the versions.

Example - R7

"THIS INVITATION IS FOR YOU ONLY - PLEASE DO NOT FORWARD IT TO OTHERS.

You are invited to attend an online , Event ID: on . (To see the Event’s start time in your time zone, click the following link: )

The field, after saving and re-opening in R6.5, looks like this :

“THIS INVITATION IS FOR YOU ONLY - PLEASE DO NOT FORWARD IT TO OTHERS.
You are invited to attend an online , Event ID: on . (To see the Event’s start time in your time zone, click the following link: )
