Xadmin report wraps text over 2 lines (unwanted)

Hi,

I have several reports that work perfectly in Xstore but when I run the same report in Xadmin, then fields are wrapped over 2 lines.

Even when the reserved space is long enough.

See the image below from Xadmin:

While exactly the same report in Xstore, shows the following:

Does anyone knows what causes this in Xadmin?

I only see it happen for reports that I create myself, so it does not happen in the base reports that were provided with Xstore, so I presume it is some setting in the jrxml file or in iReports that causes this.

I hope someone has seen this before and was able to fix it.
