Default basic load input

Sorry for this very basic question but I am new to this software and getting my head round it.

I have part of an attic roof load to support on an opening, Catnic have told me the load is 40Kn and the span is 1885mm. I cant use a lintel for this load as it would be too tall, hoping a small beam might do.

I have tried entering the span as above with a w1 load of 40, but the software then tells me I have a total load of 75.4Kn, which has thrown me a little. I assume I am interpetting the instructions wrongly?

any help appreciated
