Problems with rich text

I am using a piece of business administration software which uses fastreport to output information and have recently ran into an issue I am unable to resolve. I am getting two different outputs from the same variable in different reports. When I run a report from the "aftersales" section the output is normal as below.

wrote:

New Hood

Remedials sheet 18/12/2014

1 - Supply and fit tops-cut, upstand and top where coffee machine to fit.

2 - Template glass (mantle will need dismantled to fit).
(and so on)

However, when I run a report from the "aftersales reports" section the output appears as below.

2.

In both cases I have used an RTF object with the same parameters. The only thing that differs are the data set values.

Data field: Description (COMPLAINT)
Data set: Complaint details

as opposed to

Data field: Description (COMPLAINT)
Data set: AFTERSALES

When I leave the data field and set blank I get

2.

Which is missing the rtf tags but is also missing the rest of the data from the field.

The variable i am using is [Customer details."Description (CUSTOMER)"]

I am not sure what I can do to resolve this issue or if it can be resolved.
