Unwanted empty page in documentclass "scrartcl"

I’m currently writing the exposé to my thesis in texstudio and as I want to start the bibliography on a newpage I put newpage after my last section.
The last section ends on an even numbered page, but still when compiling there will be an empty page between my last section and the bibliography.

Openany in the documentdefinition seems to only work for the documentclass{book}, and neither the [oneside] option nor the command letcleardoublepageclearpage change this behaviour.
Thank you for trying to help.
