Universe Designer not pulling in Long Text from BEX Query

We are creating universes against BEX Queries (using BO 4) and the Designer tool always brings in the short Text for each object, despite BEX being told to use the Long Text.

I don't see any settings in Designer that are used to determine which SAP defined text field to use. There is the setting which is used to determine the character length of object names; we currently have this set to 1000 which should accomadate any Long Text fields.

Any have any suggestions or solutions?

Thanks
